How to Manage Passwords Securely
Practical password security: use a password manager, create unique long passphrases, enable 2FA, avoid reuse, and learn why 'strong but reused' is still a risk.
Quick Answer
Secure password management means storing unique, long passwords in a password manager, enabling two-factor authentication everywhere possible, and never reusing passwords across important accounts.
Definition
Password security is the set of practices that keep credentials safe — generating strong unique secrets, storing them securely, and layering authentication with a second factor.
Answer first
Use a password manager, generate unique long passphrases, enable 2FA, and stop reusing passwords.
1. Use a password manager
A manager generates, stores and fills unique passwords for each account. This is the single most effective hygiene change.
2. Create long, unique secrets
Length beats complexity. Prefer passphrases (several random words) that are unique per site over short mixed-character passwords you reuse.
3. Enable two-factor authentication
2FA (authenticator app or hardware key) protects you even when a password is leaked. Prefer an authenticator app over SMS where possible.
4. Check your password strength
Test a password’s strength estimate locally before using it (never paste your real password into unknown sites).
5. Recover from a breach
If a service announces a breach, change that password everywhere it was reused, and enable 2FA if not already enabled.
