I’d prefer Proton Auth to have a simpler interface, similar to Google Authenticator, where it only displays the website or brand name and the authentication code. The current use of logos often results in incorrect or pixelated images, and requiring an issuer to avoid displaying “No Issuer” adds unnecessary information. I’d like Proton Auth to focus on a minimal design that makes it easy to search for a website and immediately find its authentication code.

I've added a visual representation of what I'm suggesting below.
