Yandex TOTP

Yandex has its own algorithm for generating one-time passwords. The link format looks something like this

otpauth://totp/test:me?secret=3XCGNQJBC3*******************AAKUYYHJNKXY%3D%3D%3D%3D%3D%3D&algorithm=SHA256&encoder=yandex&digits=8&period=30

Here is a working plugin for KeePass GitHub - norblik/KeeYaOtp: A Keepass plugin that generate one-time passwords for Yandex 2FA

So they are using SHA256 instead of the usual SHA1 and generating 8 numbers instead of usual 6.

Yes, it would be nice if Bitwarden supported the full spec of that URI, not just for Yandex but anything that decides to use different parameters.
