Security Keys / U2F authentication doesn't work with Vendetta

[schmensch]

Discord recently added support for Security Keys / U2F (e. g. Yubikeys) as a second factor to secure your account. Trying to logging in to an account secured by such a key doesn't work with Vendetta.

Steps to repoduce:

• Set up a Security Key on Desktop Discord (Settings --> My Account --> Register a new security key)
• You will be automatically logged out of Vendetta
• Enter your credentials again
• Upon clicking "Authenticate with security key", Discord / Vendetta just says "An error occured. Please try again"

Expected behaviour:

• Upon clicking "Authenticate with security key", Discord should display the Android WebAuthn prompt, where the user authenticates with their security key
• Following this, the user is then logged in to Discord / Vendetta

You might be able to work around this by still having the older Authenticator 2FA enabled and using it instead

Does it work with the original Discord app?

[schmensch]

Yes, it works as described in the expected behaviour.

Exact same behaviour here on Latest Vendetta app.
Works with no problem on original Discord app.
