How to Create Strong Passwords (and Actually Remember Them)

A strong password is long, unique and stored safely. Reusing one clever password across many accounts is still risky because one breach can expose every account.

Start with the idea

Length generally improves resistance to guessing. Uniqueness prevents a stolen password from unlocking other services. A password manager can generate and store different credentials for each account.

Multi-factor authentication adds another barrier. Prefer authenticator apps, passkeys or security keys when available, while keeping recovery options current.

Worked example

A short password with predictable substitutions can be easier to guess than a long random password. A generated password such as several unrelated random words or a long random character string gives more possible combinations.

Do not copy sample passwords from an article. Generate a new value locally and save it directly in a reputable password manager.
