In-Browser Password Managers: Safe but Limited

In-browser password managers are found in all the most popular browsers, including Safari, Chrome, Firefox, and Edge. They all use 256-bit encryption. Some add even more protection via master/primary passwords, similar to the functionality found in third-party password manager apps like 1Password.

However, in-browser password managers lack some functionality found in third-party apps. This makes them unsuitable for users with advanced needs.

Pros of In-Browser Password Managers

  • Free
  • Easy to use
  • No downloads required

Cons of In-Browser Password Managers

  • Can’t share passwords with others
  • No ability to auto-fill passwords in other browsers
  • Unable to customize auto-generated passwords

From a safety standpoint, in-browser passwords – when used with additional security measures like password-protected access to your device and two-factor authentication – are relatively safe. Whether you choose them over a third-party password manager application, depends on the functionality you need.

In today’s tech-driven world, most of us rely on the internet to manage our day-to-day lives. From checking in on social media to reading emails to paying bills, we log in online multiple times each day.

People serious about managing online risk often rely on password managers as part of their security strategy. These convenient tools create computer-generated passwords that are complex, unique, and difficult for hackers to figure out. Password managers also keep your private information safe in a secure, encrypted location.

There are two types of password managers: third-party apps and the password manager built into your web browser. Password manager apps are plentiful on the market, and we’ve written about them before. We’ve reviewed many and recommend several, including 1Password, Keeper, Abine Blur, and NordPass.

But what about the password manager found in your favorite browser? Will it meet your needs? More importantly, is it safe? Read on to find out if the built-in password managers found in Chrome, Safari, Firefox, and Edge are right for you.

Are Browser Password Managers Safe?

For many years, security experts recommended never saving passwords in your browser. Historically, third-party password managers offered better encryption than their in-browser competitors. They also eliminated the risk of your passwords falling into the hands of someone who gains access to your computer, either physically or remotely.

Today, the use of two-factor authentication (2FA) makes in-browser password managers safer, and reduces the risk of unwanted computer access. With this feature turned on, anyone trying to access your account needs more than just your password to succeed. In terms of additional safety, the browsers in Safari, Chrome, Firefox, and Edge all offer encryption, and protect your saved passwords with the same security used to keep your email, cloud storage, and devices protected.

The truth is, no password manager is failsafe. Even third-party apps have been shown to have security flaws. Even so, password manager apps do incorporate stronger security measures that are needed to ensure the security of their additional functionality (like password sharing and cross-browser availability of data).

However, the companies behind today’s most popular browsers continue to invest heavily in strengthening their security protocols to create a safe and secure environment. Additional safety precautions a user can take, like password-protecting your computer, locking it whenever you are away, and turning on two-factor authentication, add to your overall safety.

Today, every major browser offers a password manager that uses encryption to keep your information secure. But there are some differences in functionality among the big four – Safari, Chrome, Firefox, and Edge.

Safari Password Manager: Best for Apple Fans

If every device you own has a stylized fruit symbol on it, Apple’s iCloud Keychain is a natural choice for your password manager. It comes pre-installed on every Mac, iPhone, and iPad. You’ll need an iCloud account to use Safari’s password manager. If you’re already using an iPhone, iPad, or Mac (or all three), you likely have an iCloud account.

To use iCloud Keychain, you’ll need to enable the feature on each Apple device. Keychain will sync your passwords automatically across every enabled device.

How to turn on iCloud Keychain on your Mac

  1. Choose the Apple menu and go to System Preferences.
  2. Click Apple ID, then iCloud in the sidebar.
  3. Tick the Keychain box.

How to turn on iCloud Keychain on your iPhone and iPad

  1. Tap Settings, then tap [Your Name], and choose iCloud.
  2. Scroll down and tap Keychain.
  3. Slide to turn on iCloud Keychain*.

*You may be prompted for your Apple ID password to complete this step.

Once enabled, iCloud Keychain will operate in the background. It automatically generates a complex password whenever you create new login credentials on a website. You can also create and save your own passwords. Keychain autofills your saved password on every device where the Autofill feature is activated. Other iCloud Keychain features include notification of passwords involved in data breaches and alerts when it thinks the passwords you create are too weak.

How iCloud Keychain protects your data

Apple uses end-to-end 256-bit AES encryption to protect your data. It combines a unique key made from information specific to your device with a passcode you create. This encryption technology means no one else can read your data, not even Apple.

Safety considerations

While this is a very safe approach to protecting your data, iCloud Keychain does have an obvious downside. If you don’t have all your devices password protected, anyone with your phone, tablet, or computer has your passwords at their fingertips. It’s important to always require password or biometric access to your phone, tablet, and computer. You’ll also want to enable two-factor authentication for an additional layer of protection.

Google Chrome Password Manager: Great across operating systems

Not loyal to one operating system? Google’s password manager works wherever you use the Chrome browser. Chrome doesn’t care if you’re on an Android, Windows, or iOS device. Google offers Chrome apps for all operating systems.

The password manager found in Chrome is tied to a user’s Google account. You must be signed in to your Google account to use this feature. When you are, your passwords are saved in your Google account and synced on all devices where you’re using Chrome. To enable this, turn on the Chrome sync feature on each device.

How to turn on Chrome Sync on your computer

  1. Open Chrome.
  2. Click Profile in the top right of your screen.
  3. Click Turn on sync.
  4. Log in to your Google Account.
  5. Click Yes, I’m In to turn on sync.


How to turn on Chrome Sync on your Android device

  1. Open the Chrome app on your Android phone or tablet.
  2. Tap More, then Settings, then Turn on sync.
  3. Select the account you want to use.
  4. Tap Yes, I’m In to turn on Sync.

How to Turn On Chrome Sync on iPhone and iPad

  1. Open the Chrome app on your device.
  2. Sign in to your Google Account.
  3. Tap More …, then Settings.
  4. Choose your Account Name.
  5. Tap Sync.

Chrome’s password manager will generate complex and unique passwords for each site. You can also create and save your own.

How Chrome Password Manager protects your data

Google uses AES 256-bit SSL/TLS encryption for passwords. Google’s passphrase feature offers an additional layer of security. Passphrase creates a unique primary password that nobody knows, except you. Even Google cannot access your unique passphrase. With Chrome’s built-in Password Checkup feature, you can see if your login credentials have been involved in a data breach. This feature is turned on by default.

Safety considerations

Although Google takes steps to protect your data with encryption and a passphrase, there are still safety concerns. Anyone who can access your device also has your passwords. It’s important to password-protect all your devices. Enabling two-factor authentication boosts security even more.

Perhaps one of the bigger concerns for users is data sharing. When you use Chrome password manager, you send all your information to Google, a company in the business of capturing and using data for profit. While there are no known cases of Google compromising account holders’ private information in this way, it is something to think about. You can read more about general browser safety here and here.

Firefox Password Manager: Best for privacy and limited data sharing

People serious about their online privacy often turn to Mozilla Firefox as their primary browser. Mozilla, the parent company of Firefox, is a non-profit entity with a main focus of online security.

Firefox offers a built-in password manager and syncing across devices. It works on different operating systems. You’ll need to sign up for a Firefox account and enable Firefox Sync to save and share passwords across devices. But unlike setting up accounts in Google, Microsoft, or Apple, your Firefox account won’t be tied to other services, like email or cloud storage.

How to create a Firefox account and turn on Firefox Sync on your computer

  1. Open the Firefox browser.
  2. Click the Profile Icon in the top right corner.
  3. Enter your email address.
  4. If you are creating a new Firefox Account, you will be prompted to create a password and enter your age (required).
  5. Choose what to sync.
  6. Click Create Account.
  7. You will be prompted to add a second device. Follow the prompts on that device to complete your Firefox Account and Sync setup.


As with other in-browser password managers, Firefox will generate strong passwords for you. You can also create and save your own. Firefox Lockwise auto-fills your passwords across devices. It operates behind the scenes on your computer, and has a separate app for your phone or tablet.

How Firefox Password Manager protects your data

Firefox uses 256-bit AES encryption to protect passwords. Enabling the Primary Password feature of Firefox adds an additional layer of safety to the passwords you save. Firefox Monitor alerts you if your passwords were involved in a data breach.

Safety Concerns

Just as with the other browser-based password managers, your information is only as safe as your device is protected. Incorporating password protection on your phone, tablet, and computer adds a layer of protection. Firefox also offers two-factor authentication, which should be enabled.

Edge Password Manager: Ideal for Microsoft Account users

If you already have a Microsoft account, it’s convenient to use the password manager in Edge. When you activate sync, your passwords are available in the Edge browser on every device where you’re logged in to your Microsoft account. If you don’t already have a Microsoft account, you’ll need to create one.

How to turn on Edge Sync on your computer

  1. Select your profile image in the Edge taskbar.
    Note: If you see Manage Profile Settings, you are already logged in. If not, you’ll receive a prompt to log in to your account (proceed to step 3).
  2. Select Manage Profile Settings > Sync > Turn on Sync.
  3. Click Sign In and enter your credentials, then click Continue.
  4. Choose Sync when prompted.


How to Turn On Edge Sync on Your Mobile Device

  1. Download the Microsoft Edge app for iOS and Android.
  2. Sign in to your Microsoft account.
  3. Tap Sync.

When you are creating new website login credentials, Edge will auto-generate a complex password. You can also create and save your own. Edge password manager works across multiple browsers and devices. To enable auto-fill on Chrome, you’ll need the Microsoft Autofill extension. For Android and iOS devices, you can autofill with the Microsoft Authenticator app.

How Edge Password Manager protects your data

Microsoft Edge uses AES-256 encryption to protect your confidential information. Microsoft also recently rolled out the Microsoft’s Password Monitor. This new feature informs you if one of your passwords is identified in a security breach. It also prompts you to change the compromised password. While other browser password managers also offer this feature, Microsoft is unique by using homomorphic encryption, a newer cryptographic technology.

Safety concerns

As with Chrome, Firefox, and Safari, the Edge password manager is safe as long as your device doesn’t fall into the wrong hands. Always turn on password protection on all your devices. Although Edge does not offer an extra option to set a master password within the password manager itself (a feature both Chrome and Firefox offer), you can further secure your Microsoft account with two-factor authentication. You should turn this feature on.

Should You Use an In-Browser Password Manager?

Like all technology, in-browser password managers aren’t a magical solution to every security issue. They offer benefits, but also have limitations. When deciding whether to use an in-browser password manager, it comes down to the functionality you need.

For users who don’t need to share login credentials with anyone, an in-browser password manager is a viable option. The same goes for users who stick to a single browser whenever they’re surfing the web. In-browser password managers are also already installed with your browser, eliminating the need for you to download anything.

For users who want or need more functionality than an in-browser password offers, third-party password manager apps are the logical choice. These apps also include a higher level of encryption that is needed to support their additional functionality.

Other Ways to Increase Your Online Safety

Whether you choose the password manager in your favorite browser or a third-party app, staying safe online is a priority. Password managers are one of many tools to help you do that.

Besides securing your passwords, there are other ways to protect yourself and your confidential data. Install and run an antivirus program. There are several free and paid options we recommend. Antivirus software runs behind the scenes, and quickly detects and resolves problems before they escalate.

Another way to stay safe is to maintain your privacy while browsing the web is with a virtual private network (VPN). VPNs do three things very well. They make you anonymous on the internet, help to keep hackers and cybercriminals away from your devices, and allow you to access potentially blocked websites.

Don’t forget to password-protect all your devices, and use two-factor authentication on your accounts whenever it is available. This multi-pronged approach is the best way to stay safe in today’s online world.

In-Browser Password Managers: Frequently Asked Questions

Still have questions about using an in-browser password manager? Check out our most frequently asked questions for more information. Not seeing what you need? Drop a comment below. We’re always happy to help you out.

All in-browser password managers are directly tied to the safety of your device. If you take extra steps to secure your computer, phone or tablet – by using password protection for access, then your browser’s password information is safe. Likewise, turning on two-factor authentication wherever it is offered, adds an extra layer of protection.

If you are still concerned about in-browser password manager safety, you should consider using a third-party password manager app, like 1Password. These services offer additional functionality, and enhanced security to support this functionality.

Both Chrome and Firefox offer the opportunity to set a primary password, a feature not found in Safari or Edge. This primary password acts as an additional layer of security. If someone should gain access to your device or your account tied to the browser, they would still need to know this additional piece of confidential information to get to your password data. Since Chrome is owned by Google, which isn’t too keen on privacy, the safest in-browser password manager is that offered by Firefox. You can read our full review of these managers in this article.

All the major in-browser password managers rely on end-to-end encryption to keep your data safe. This is the same technology that keeps your email and cloud storage protected. Likewise, all browser password managers are tied to your account (e.g. Google Account, Apple ID) for the respective browser. So, the security applied to your general account acts as an additional layer of protection against accessing your password data.
