A strong password is difficult for other people or automated systems to guess. Good password habits can significantly improve account security.
Make passwords long
Length is an important part of password strength. A longer password or passphrase generally provides more possible combinations than a very short one.
Avoid predictable information
Do not base important passwords on easily known information such as your name, birthday or simple sequences.
Use different passwords
Reusing the same password across multiple services creates a major problem: if one service is compromised, attackers may try the same password elsewhere.
Use a different password for each important account.
Consider a password manager
A reputable password manager can generate and store unique passwords so you do not have to memorize every one. Protect the manager with a strong master password and appropriate security settings.
Do not share passwords
Avoid sending passwords through ordinary messages or giving them to people who do not need them.
Combine good passwords with 2FA
A strong password works best as part of a broader security approach. Enable two-factor authentication where available, keep software updated and be cautious about suspicious login pages.
The goal is not to invent a clever password you can reuse everywhere. The goal is to use unique, difficult-to-guess credentials and protect them properly.
