Most of the time, you would use a time based one time password. You can generate and verify the token with HOTP:

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
