Authpermit Assurance Levels
| Level | Meaning | Typical evidence |
|---|---|---|
| RAL0 | Self-asserted | Form input |
| RAL1 | Basic digital verification | Email/phone possession |
| RAL2 | Document verified | OCR + MRZ + authenticity |
| RAL3 | Document + biometric | + face match + liveness |
| RAL4 | + authoritative source | + issuer/database confirmation |
| RAL5 | Cryptographic / issuer-backed | Signed credential, chip verification |
Levels map internally to NIST SP 800-63-4 identity assurance concepts without copying their terminology. A verifier requests a required level; Authpermit determines the checks.
