Password Security
Methods for creating and managing credentials that resist unauthorized access.
Password security is the practice of creating, storing, and using passwords in ways that make account takeover less likely. Reuse is dangerous because a password exposed at one service can be tried elsewhere. Unique passwords and a reputable password manager reduce this shared risk.
Use long, unique passwords or passphrases for each service, preferably generated and stored by a password manager. Turn on multi-factor authentication, secure the manager with a strong unique credential, and protect its recovery process. Change a password promptly when there is evidence it was exposed; frequent arbitrary changes can lead to predictable patterns.
A convincing message or page can still be a phishing attempt. Navigate to important services using a saved bookmark or known address, check the domain before signing in, and do not share one-time codes with callers or messages. Passkeys can resist many phishing attacks because authentication is tied to the legitimate site.
