How Password Managers Work
A password manager encrypts your stored passwords with a key derived from your master password. The encrypted vault is stored locally, in the cloud, or both. When you need a password, you unlock the vault with your master password and the manager fills in credentials automatically. The encryption is strong enough that even the service provider can't read your passwords.
Generating and Saving Passwords
The workflow is simple: when creating a new account, generate a strong random password with your preferred tool, copy it, and paste it into both the sign-up form and your password manager. Label it with the site name and your username. From that point, you never need to type or remember that password — the manager handles everything.
Choosing the Right Manager
The main options are Bitwarden (open-source, free, audited), 1Password (excellent UX, paid), and KeePass (offline-only, maximum control). Browser-built managers from Google and Apple are convenient but offer less flexibility. Open-source options are generally preferred by security professionals because their code can be independently audited.
Protecting Your Master Password
Your master password is the single point of failure, so it needs to be exceptional. Use a passphrase of 5-6 random words (diceware method) for memorability combined with high entropy. Enable 2FA on your password manager account where available. Store your emergency recovery kit — master password written down — in a physically secure location like a safe.
A password manager transforms the impossible task of remembering hundreds of unique random passwords into a trivial one. Set one up today and use it in combination with a random generator for every new account.
