5. Supported tokens

LinOTP supports a broad range of different tokens from different vendors.

HOTP

Supports any kind of RFC 4226 compliant tokens. LinOTP can import OATH-compliant key files according to RFC 6030. Additionally it can import SafeNet eToken PASS XML files and Feitian XML files. Furthermore the key can be entered manually during enrollment. Thus LinOTP supports:

  • SafeNet eToken PASS
  • Feitian C100
  • Authenex A-Key V3.6
  • Safeword Alpine
  • Validustech BC-30, CR-1, PB-1
  • Many different kinds of mobile Apps. See section Recommended Mobile Apps.

HMAC-SHA256

Supports HMAC-SHA256. Other than RFC 4226 which is based on HMAC-SHA1 LinOTP also supports HMAC-SHA256. This is used e.g. with newer SafeNet eToken PASS tokens.

TOTP

Supports any kind of TOTP compliant tokens. LinOTP can import OATH-compliant key files according to RFC 6030. Furthermore the key can be entered manually during enrollment. Thus LinOTP supports:

  • SafeNet eToken PASS timebased
  • Feitian C200
  • Validustech BC-30, CR-1, PB-1

SafeNet eToken NG-OTP

Supports the eToken NG-OTP. LinOTP can generate the HMAC key on the eToken NG-OTP.

Yubico Yubikey

Supports the Yubikey I, Yubikey II and Yubikey NANO in OATH mode. LinOTP can generate the HMAC key on the Yubikey.

Also supports the Yubikeys as shipped by Yubico with the originial Algorithm, creating the 44 character long password. The authentication is then forwarded to the Yubico cloud authentication API.

Vasco

Supports DigiPass Tokens in RO (Response Only) mode like GO1, DP300, GO3, GO6.

mOTP

Supports mOTP. LinOTP supports the motp1 Algorithm. The mOTP key can be entered during enrollment. For recommended apps see section A.

Simple Pass

Supports the Simple Pass Token, which is a fixed password token without any moving factor.

Remote Token

Supports Remote Token, which forwards OTP requests to other LinOTP servers, either based on user assignment or simply based on the token serial number, thus enabling complex distributed setups.

RADIUS Token

Supports RADIUS Token, which forwards the authentication request of username and password/OTP to any given RADIUS server, thus enabling smooth migration scenarios.

SMS OTP

Supports SMS Token. LinOTP can enroll SMS Token, which will send OTP values via SMS to the given cell phone number of the assigned user.

Day OTP / Tagespasswort

Supports Tagespasswort Tokens. LinOTP can import key files or enroll Tagespasswort Tokens, which will changes their value once a day and thus enable the usage of OTP in Applications that do not provide any external authentication interface like e.g. RADIUS.

E-Mail Token

This token is used in challenge/response mode. This means that the user triggers LinOTP to send an e-mail (challenge) containing the OTP and then replies with that OTP (response). The e-mail address where the OTP is sent can be configured when assigning the token to the user.
