Password Manager

Reviewed byCybersecurity entrepreneur & security researcher

What is Password Manager?

Password ManagerAn application that generates, stores, and autofills strong unique credentials, secured by a master passphrase and increasingly by passkeys.


A password manager keeps an encrypted vault of credentials and secrets that the user unlocks with a single master passphrase and ideally a second factor. The client generates long random passwords per site, autofills them only when the page origin matches the saved entry (which mitigates phishing), and syncs across devices via end-to-end encryption. Modern tools — 1Password, Bitwarden, Dashlane, Keeper, Apple Passwords, Google Password Manager — also store TOTP seeds, passkeys, secure notes, and SSH keys, and offer enterprise features like SSO, SCIM provisioning, breach monitoring, and shared vaults. Risks include vault compromise via master passphrase phishing, malware on the endpoint, and supply-chain attacks against the vendor.
