Icon for TOTP provider app

[MorrisJobke]

Sadly I have no real idea what an icon could look like, but maybe @eppfel or @skjnldsv or any other in @nextcloud/designers has an idea.

Then we could also use this in the personal settings (see nextcloud/server#3151) as sidebar icon.

Yup I remember @jancborchardt and I talked about that at the Winzerhof hacking when I made the u2f logo. I think a phone icon could fit this app.

With a key inside?

Or maybe with a key next to it? This is how the new Nextcloud Phone Sync logo could look like: nerzhul/ncsms-android#118 (comment)

I think adding it beside, adds too much details compared to the other icons.

What about a small keyring with 2 keys on it? Heh, looks like someone else had the same idea (although I'd make the ring a bit smaller to give the keys more emphasis):
