Hello Microsoft Authenticator Team,

We are an enterprise customer using the Microsoft Authenticator App for TOTP, and we have algorithm=SHA256, but it always defaults to SHA1. We request a feature in the Microsoft Authenticator App to support SHA256, SHA384, and SHA512 algorithm-based TOTP since we have an internal app that requires this. 

otpauth://totp/example.com :Administrator?secret=XXXX&issuer=example.com&algorithm=SHA256&digits=6&period=30
