Why MFA Does Not Replace Good Technology Practices
Multi-factor authentication is an important security control, but it does not make every other technology decision irrelevant.
MFA protects an authentication step
It can make stolen passwords less useful. That is valuable.
Other risks remain
Devices can still be compromised, data can be deleted, accounts can be misconfigured and services can become unavailable.
Recovery matters
If a user loses access to their authentication method, the business needs a safe recovery process.
Access should still be appropriate
Users should have the access they actually need. MFA does not make excessive permissions harmless.
Security is layered
Good security combines appropriate authentication, updates, backups, access controls, network design, user awareness and recovery planning.
MFA is a strong layer. It is not the whole security strategy.
