Hey everyone, I implemented MFA on my self hosted application. I updated the totp config to set the issuer to my application’s name, But I want to set a Logo for my application that will be displayed on the user’s chosen Authenticator app like authy. I can’t seem to find the option to modify this.

I'm not too familiar with that but it seems that services will just look for a logo themselves... from an authy help article:

As the vendor of an application, how can I change the logo associated with my application’s account token?

There are two different scenarios with different solutions. If you are using the Authy API to generate your Authy account token, then you can change the logo in Twilio Console. If you are not using the Authy API, then the Authy app uses Google Image Search API to find a logo, using your Google Authenticator token’s Issuer name as the default search term. The user can also try other search terms to find a better logo. The search results may not be perfect 100% of the time, because Google Image Search isn’t perfect. If you recently changed your application’s logo, it may take some time for Google to figure out that that is the most relevant logo for your application’s name. In general, we will not change your application’s logo to something different than what is returned by Google.
