How to Choose a Password Manager

Why You Need a Password Manager

The average person has over 100 online accounts. Using unique, strong passwords for each one is impossible without a password manager. Password reuse is the leading cause of account compromise: when one service suffers a data breach, attackers try those credentials on every other service. A password manager generates and stores unique passwords, eliminating this risk entirely.

Modern password managers also store secure notes, credit card details, and identity information, making them a central hub for your sensitive data. The convenience of auto-filling login forms means that using a password manager is actually easier than trying to remember passwords manually.

Key Features to Look For

Zero-knowledge encryption is non-negotiable. This means the provider cannot access your vault, even if their servers are compromised. Your master password should never leave your device unencrypted. Look for AES-256 encryption or XChaCha20-Poly1305 as the underlying cipher.

Cross-platform support is essential. Your password manager should work on all your devices and browsers seamlessly. Check for browser extensions for Chrome, Firefox, Safari, and Edge, as well as native apps for Windows, macOS, iOS, and Android. Auto-fill should work reliably across all platforms.

Cloud vs Local Vaults

Cloud-based password managers like Bitwarden and 1Password sync your encrypted vault across devices automatically. This is convenient and secure, provided you trust the provider's infrastructure. Your vault is encrypted locally before being uploaded, so the cloud provider cannot read your passwords.

Local-only password managers like KeePass store your vault as an encrypted file on your device. You control where the file lives and how it is backed up. This offers maximum control but requires manual syncing between devices, typically using a service like Syncthing or a cloud drive. Choose local storage if you have a high threat model and are comfortable managing your own backups.

Open Source Matters

Open-source password managers allow independent security researchers to audit the code for vulnerabilities and backdoors. Bitwarden, KeePass, and Proton Pass are all open source and have undergone third-party security audits. Closed-source managers require you to trust the company's claims without independent verification.

This does not mean closed-source options like 1Password are insecure. They have strong reputations and undergo regular audits. However, open source provides an additional layer of transparency that is particularly valuable for a tool that holds your most sensitive data.

Pricing and Value

Bitwarden offers a generous free tier that covers most individual needs. Premium features like advanced 2FA support and emergency access typically cost around eight to ten pounds per year. 1Password starts at roughly three pounds per month and includes family sharing options. Proton Pass is included with Proton's paid plans and integrates well with their email and VPN services.

Free options from browser vendors like Chrome and Safari are convenient but limited. They lack cross-platform flexibility, advanced features, and the security focus of dedicated password managers. Investing in a proper password manager is one of the most cost-effective security decisions you can make.
