Generation algorithm / firmware OTP Actividentity mini token

Question

Information Security

Good day to all!
There is a one-time password generator (OTP) ActivIDentity mini token.
And two questions:
1) the one-time password generation algorithm is of interest, there seems to be nothing in google.
2) as far as I understand, a key is used to generate a password, sewn into the token itself. How can I find out (and even better - sew up a new one) the key?
Thanks in advance!

Answer 1

1) it’s even in the RFC, not like in Google
2) find out - no way, flash your own - no way

Answer 2

1) There are 3 standard (OATH) generation algorithms: HOTP, TOTP, OCRA
2) You cannot flash it into a hardware token - this is how the manufacturer intended

Answer 3

2) Recently, Protectimus Slim mini TOTP tokens have appeared on the market , which are reflashed via NFC. I connected this to my Google account instead of Google Authenticator, I also tried to connect to Facebook and Vkontakte, it works. I think these might work for you too.
