A strong password should be long, unique, and difficult for someone else to guess.
Length matters. A longer passphrase made from several unrelated words can be easier to remember and harder to crack than a short, complicated password.
The most important rule is not to reuse passwords. If the same password protects several accounts, one breach can expose them all.
A password manager can help employees create and store unique passwords. This is usually safer than writing passwords on sticky notes, saving them in a spreadsheet, or trying to remember dozens of similar passwords.
MFA should still be used even with strong passwords.
Businesses should avoid forcing employees into patterns that encourage weak behavior, such as changing passwords so often that users simply add a number to the end.
Good password security combines unique passwords, secure storage, MFA, and fast response when credentials are exposed.
