Installation

pip install nopassword

Usage

The generated passwords are stored in your clipboard, enter a seed/key to generate a password

nopassword seed

Example

Generate password using “facebook” as seed

nopassword facebook
6n1eby^@]{dm6T-{]r{5NC^Z^`%vZ9w4.nemgcrN-v&,|,gS3fn]KzXRH,br"$=zf*"v_q@j@

Generate password using “github” as seed

nopassword github
k/Mzz-$6AQ\K`1n/mD7]1o0|E'b};RO*ZLzCC]Iuo!oJ#}oB2+a~rx{:o;}&R|O*5k*+u~,%@

As this is determenistic, “github” again will generate the same result

nopassword github
k/Mzz-$6AQ\K`1n/mD7]1o0|E'b};RO*ZLzCC]Iuo!oJ#}oB2+a~rx{:o;}&R|O*5k*+u~,%@

Two factor password generator?

I’d like to think so. Something you got: key file and something you know: seed, iterations and alphabet.

So for a attacker to be able to generate your password they need the keyfile and the parameters.
