I'm Ideating on offering Scan QR Code to Login as a Service.How it works?
1. Add your account to my authenticator app.
2. Whenever you need to sign-in, scan the QR code displayed on the website from my authenticator app.
3. Enter your device pin or use TouchId/FaceId and you will be logged in on the website.My service will manage the generation of the QR codes, the authenticator app, etc. I also think 2FA will not be needed when using this as my authenticator app will check two factors -
1. If the request is being made from the device which the users posses.
2. The passcode/biometrics of the phone.I think my service will be really useful for no-code/low code websites as well as websites which do not have a native mobile app. Please let me know what you think about this idea.PS - I'm not sure if it's ok to post this on HN, please let me know if it's not ok and I'll take it down.
