Authentication methods in IAM
Airlock IAM supports many authentication methods that may be combined into authentication flows.
Note that Airlock IAM also provides authentication method-related user self-services - such as token migration and token self-management facilities - and token management features.
An authentication method can support one or multiple authentication factors.
Examples:
- Authentication method mTAN supports OTP as the only factor.
- Authentication method Airlock 2FA supports the following factors: Push, OTP, QR-Code, and challenge-response.
In general, strong authentication requires the combination of at least two different categories of authentication factors.
Factor categories:
- Possession – something that a person proves to have. This could be a physical or virtual possession such as a hardware OTP token, a certificate USB stick, or a smartphone.
- Knowledge – something that a person knows. This could be a username/password combination, the correct answer to a challenge, etc.
- Inherent – some physical attribute that is associated with a person. This could be a fingerprint, iris scan or a voice sample, etc.
