2FA and MFA: Do you still need strong passwords?
MFA does not replace good passwords. It reduces login risk, but weak or reused passwords remain an attack vector.
Why MFA is not a license for weak passwords
Multifactor protection is extremely valuable, but it does not eliminate the risks of weak or reused passwords. Above all, it reduces the success rate of certain login attacks.
If the password itself remains bad, problems with phishing, fallback flows, recovery processes or internal security gaps arise.
How password and MFA work together
- A strong password prevents trivial takeovers and makes offline attacks more difficult.
- MFA further protects the login, even if a password is revealed.
- Only the combination of both creates robust everyday safety.
Which accounts have priority
Email, banking, work accounts, cloud storage and password managers should always be secured first. These accounts often determine access to everything else.
If you're using MFA selectively, start there, not on less critical services.
Quick checklist
The most important actions from this guide in compact form.
- Continue to keep strong, unique passwords as a basis.
- Enable MFA first for email, password managers, and critical financial or work accounts.
- Store recovery codes safely so that MFA does not become a problem in the event of an emergency.
