Can’t you just use a HOPT/TOPT so the user can scan a QR code with e.g google authenticator? Check https://github.com/pyauth/pyotp for more information
Project mention: Ente: Open-Source, E2E Encrypted, Google Photos Alternative | news.ycombinator.com | 2024-03-01probably better to look into projects like this one https://github.com/Bubka/2FAuth
Project mention: PyPI announces mandatory use of 2FA for all software publishers | /r/programming | 2023-05-30Huh? Who is saying you need a smartphone? PyPi accepts TOTP as 2FA. TOTP is an open standard that has been around for at least a decade already and is very easy to implement, literally 20 lines of python. There are a ton of TOTP applications available, from CLI, to GUI on desktop systems, to Android apps, iOS, etc. If you have any device, be it a computer, phone, tablet, etc., which you do since you need one to publish the code from, you can easily generate TOTP codes. Heck, you could even do it by a hand on a paper.
I'm using https://github.com/Spomky-Labs/otphp to generate in a PHP Backend automatically TOTPs. Something similiar is probably also available for Python/Javascript/etc.
