Type hints: your editor will love it.
No Python 2: clean code without compatible patches.
Installation¶
Installing otpauth is simple with pip
:
$ pip install otpauth
Simple Guide¶
Most of the time, you would use a time based one time password. You can generate and
verify the token with TOTP
:
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
