A Password Manager Makes Unique Passwords Manageable

Why uniqueness matters

When one website is breached, criminals may try the exposed email-and-password pair on other services. A different, long password for every account limits that domino effect, but memorizing dozens of random strings is unrealistic. A password manager stores and fills them for you, and most can generate a strong random password at signup. Its autofill can also help you notice when a page's domain differs from the one you expect.

Choose a manager thoughtfully

Compare the manager's supported devices, synchronization, export options, security documentation, and account recovery model. Decide whether a built-in browser or operating-system manager meets your needs or whether a dedicated tool offers useful sharing and organization features. Protect the manager with a strong, unique master password and multifactor authentication if available. Do not select a product solely because of a security slogan; understand where encrypted data is stored and how you can retrieve it.

Make a careful transition

Start by changing reused passwords on your primary email, financial, and shopping accounts, then continue as you sign in elsewhere. Store recovery codes and emergency access instructions separately from the vault. Treat a password-manager unlock prompt as sensitive: do not approve it after an unsolicited call or message. Keep your devices updated and lock them when unattended, because a manager cannot protect credentials on an already-unlocked, compromised device.
