Duo supports authentication using one-time password (OTP) hardware tokens such as Deepnet SafeID. There are 2 types of OTP tokens, event-based (HOTP) and time-based (TOTP), and Duo can support both event-based and timed based tokens. However, Duo does not support TOTP token drift or TOTP resync. As a result, TOTP tokens may eventually fall out of sync and generate invalid passcodes. Therefore, in long run, event-based token works better with Duo.
Deepnet SafeID provides both event-based and time-based tokens. Below is the list of SafeID tokens:

Synchronising HOTP Hardware Tokens
If you are using SafeID/Eco event based tokens (HOTP), then if you find that the OTP codes generated by the token are rejected by Duo during authentication, you may find that you need to synchronise the tokens using the following procedure;
...
Please note that only event based HOTP tokens (SafeID/Eco) can be synchronised with Duo as Duo currently doesn't support synchronising TOTP tokens.
