The browser prompt that asks with every login – “Save login credentials” – does it all without installing anything extra. On the surface, it is convenient, readily available, and sufficient.
However, a web browser is a tool designed for a browsing the internet, not for securely storing access data. The fact that it handles both processes does not mean it executes both equally well.
Read on to find out how a build-in browser “password manager” works, where its security ends, and how it differs from a dedicated solution in terms of architecture and functionality.
How your browser saves your passwords
Before evaluating the security level, it is worth understanding what actually happens to a password the moment you click “Save” in the browser prompt.
Local encryption vs. synchronization with Google, Apple, or Microsoft accounts
Traditionally, a browser saves a password locally on your device’s drive in an encrypted file. For example, Chrome uses the operating system’s encryption mechanisms; on Windows, this is DPAPI (Data Protection API), and on macOS, it is Keychain. These solutions provide a baseline layer of protection.
In practice, most users are logged into a Google account, Apple ID, or Microsoft account – and that is where a copy of their passwords goes by default. Synchronization across devices is convenient, but it means that passwords leave the device and are stored on the browser provider’s servers.
Who holds the encryption key?
This is exactly where the primary architectural difference reveals itself. In Chrome’s default configuration—and it works similarly in Edge and many other browsers—the data encryption key is linked to the user’s Google account. This means that Google possesses the technical capability to decrypt this data. This contradicts a zero-knowledge architecture.
In other words: your passwords are encrypted, but you are not the only one with access to the key that decrypts them.
Local encryption: why most people do not use it
Chrome offers the option to enable so-called client-side encryption with your own password (the “Encrypt passwords with a sync passphrase” option). Enabling this ensures that data is secured locally before synchronization – without access from Google. Technically, this is a more secure option.
However, this feature is hidden deep within the settings, requires separate configuration, and is disabled by default. Consequently, the vast majority of users never activate it…
Where browser protection ends - understand the risks
Encryption is not the only security layer, and it is rarely the critical point of failure. Below are the scenarios where a built-in browser manager falls short.
Malware
Infostealers are a category of malicious software designed specifically to steal data from browsers. They operate at the operating system level, bypassing browser encryption because they access the data after it has already been decrypted by the system. According to data from KELA Cybersecurity, in 2024 alone, nearly 3.9 billion login credential records were stolen from user devices this way.
The scenario is straightforward: a user downloads a seemingly harmless application or opens an infected file. The infostealer runs in the background, extracts all passwords saved in the browser – the password to the bank, email inbox, online store and sends them to the attacker’s server.
Physical access to an unlocked device
On an unlocked laptop or smartphone, passwords saved in the browser are accessible without additional verification. In Chrome, you simply go to Settings → Passwords to see the full list of saved data, and clicking “Show” reveals the specific password. The system does not ask for additional identity confirmation.
Any person who gains access to an unlocked device for just a few minutes – a coworker, a acquaintance, a stranger in a coffee shop – can freely browse and copy saved login credentials.
Lack of isolation from the browser ecosystem
The browser is an environment that constantly processes external content: websites, extensions, and JavaScript scripts. A vulnerability in one of the installed extensions, a malicious script on a visited page, or a compromised browser profile can all serve as vectors to gain access to data stored within that same environment. A dedicated password manager is a separate, isolated application, out of reach from the browser ecosystem.
What a dedicated password manager offers and how its architecture differs
A dedicated password manager, such as perc.pass, is designed from the ground up with one task in mind: securely storing and managing login data. This difference is not just functional, but primarily architectural.
Zero-knowledge: encryption on the device side, the key solely with the user
In a zero-knowledge model, data encryption takes place locally on the user’s device before any information ever reaches the cloud. The encryption key is a derivative of the user’s master password. The service provider never knows it, never stores it, and cannot recreate it.
In the event of a security breach on the provider’s side, an attacker only obtains an encrypted data string – entirely useless without the key, which they do not have.
No dependency on an ecosystem or manufacturer
A dedicated password manager operates independently of the browser and operating system. The same data is accessible in Chrome, Safari, Firefox, and Edge, on Windows, macOS, iOS, and Android – from a single account with a single master password. Changing a device, browser, or system requires no data migration.
Additional functional layers
Beyond password storage itself, dedicated solutions offer mechanisms that browsers do not provide:
Strong password generator – creates unique, random passwords upon every registration, without the need to invent them yourself.
Breach alerts – informs you when login data from a specific service has appeared in known databases of compromised data.
Two-factor authentication (2FA) – an additional layer of protection for the password manager itself.
browser vs. perc.pass
| Feature | Browser (Chrome/Safari) | perc.pass |
|---|---|---|
| Local encryption | ||
| Zero-knowledge model | Requires configuration | Default |
| User-held encryption key | Requires configuration | Always |
| Cross-platform compatibility | Only within the provider's ecosystem | Every browser and OS |
| Password generator | Basic | Full |
| Password strength audit | None or limited | Yes |
| Breach alerts | Partial | Yes |
| Isolation from the browser | No | Yes |
When is a browser enough, and when should you move on?
Is there a user profile for whom a browser is a reasonable choice?
Yes. A user operating exclusively within a single ecosystem (e.g., only Apple devices) who has client-side encryption enabled, uses strong and unique passwords, and protects their Apple ID account with two-factor authentication has a decent level of protection. A browser is not inherently a bad solution, but it is a solution with a limited scope of protection.
Signals that you should consider a dedicated tool
You use devices from different manufacturers or different web browsers.
You have more than a dozen online accounts.
Any of your accounts involve finance, health, or sensitive data.
You have never checked if your passwords have appeared in a breach.
You use the same or similar passwords across multiple services.
What is the simplest way to switch from a browser to a password manager?
Migration is simpler than it seems. Most browsers allow you to export passwords to a CSV file (Chrome: Settings → Passwords → Export). Dedicated password managers, including perc.pass, support importing from this format. The entire process takes just a few minutes and does not require manual data entry.
If you want to check what this looks like in practice – test perc.pass during a free TRIAL.
Importing passwords from your browser will take less time than you think.
