Engineering

What will be the future of non-SSO passwordless authentication? Currently I can think of a few: 
- SMS OTP authentication
- TOTP/HOTP Authenticator
- Email OTP or Magic link
- WebAuthn/Keychain
- OAuth 2.0 
- Sign in with Ethereum/crypto wallet 
- Login using passcode/FaceID (mobile app-specific only) 

Any others?

If you’re looking for software engineering, I’d check out /dev or /backend 

/engineering is mainly for every other engineering besides software, with the exception of embedded systems
