The 6 best password manager browser extensions

1. LastPass: Best overall password manager browser extension

The browser extension works on Chrome, Firefox, Safari, Edge, and Opera, spotting password boxes instantly as you browse. The interface is straightforward and easy to pick up, so you can start securing your accounts right away. 

When you sign up for a new account, LastPass makes up a unique password right in the form where you're typing. You can adjust how long it is and whether it includes special characters to match what the website wants. After you log in successfully, LastPass automatically saves your credentials. 

The Security Dashboard built into the extension checks your password health as you go. You'll see which passwords are weak or used on multiple sites, or if any are already stolen in data breaches. LastPass watches the dark web (sketchy corners of the internet where stolen data gets sold) and tells you if your credentials have been compromised. This means you can fix security problems easily without leaving your browser.

Comparison table: The best password manager browser extensions

What makes a password manager browser extension secure?

Ideally, your browser extension should have zero-knowledge encryption to keep passwords safe. This means the password manager encrypts your data on your device using your master password. The encrypted data is useless to anyone without your master password, so even the password manager company can't see it.

The best extensions also protect you from phishing. They recognize real websites and warn you before you type credentials on fake sites. Some extensions check web addresses against lists of known scam sites, while others use smart technology to spot suspicious page elements right away.

LastPass offers security features that monitor your password health constantly for breaches and weak spots. It also gives you two-factor authentication directly in your browser.

How do I choose the right browser password manager for my needs?

Start by checking which browsers you use most often. If you switch between Chrome at work and Safari at home, you need a password manager browser extension that works smoothly on both. LastPass syncs instantly across all major browsers, so your passwords follow you everywhere.

Especially if you shop online a lot, you'll want an extension that can autofill credit cards and addresses correctly, too. Some extensions work great with simple login forms but have trouble with multi-step checkouts or complex business sites.

LastPass also offers advanced features like password health monitoring, breach alerts, and secure sharing, while keeping the interface simple enough for anyone to figure out, even if you’ve never used a password manager before.

Why LastPass is the best password manager browser extension

Your Security Dashboard keeps an eye on password health, telling you about vulnerabilities before they become problems.
