Godkjenning

Følgende godkjenningsmetoder støttes:

Passord
Brukernavn/passord og keyboard-interactive-godkjenning. Støtter også forespørsel om passordendring.
Fellesnøkkel
Nøkkelfil (PuTTY, VanDyke's SecureCRT, SSH.com, OpenSSH, PEM), X.509-sertifikater, Microsoft Windows-sertifikater fra et sertifikatlager eller et smartkort (PKCS #11).
Kerberos v5 (GSSAPI/SSPI)
Støtte for implementeringene Microsoft Windows Kerberos (SSPI) og MIT Kerberos (GSSAPI).
Vertsbasert
Godkjenning med en vertsnøkkelfil eller et sertifikat.
RSA SecurID
RSA SecurID-tofaktorautentisering.
