Type hints: your editor will love it.
No Python 2: clean code without compatible patches.
Installing otpauth is simple with
$ pip install otpauth
Most of the time, you would use a time based one time password. You can generate and
verify the token with
import otpauth totp = otpauth.HOTP(b"user-secret") # generate a code for now code: int = totp.generate() # you may want to convert it to string str_code: str = totp.string_code(code) # verify the code totp.verify(code) # => True totp.verify(str_code) # => True
