I just checked simple login as it has iOS app also. It lets me log in with my proton account and it looks good, will test it for a while and see how it goes. It only lets you create 5 addresses so it’s the first downside I can see for now. For Firefox Relay I guess I need Firefox browser installed so I think I will pass on this one but I will definitely check out proton too as I already have proton mail. I can see they have 80% off for their Proton Pass plan now and it costs 1$ per month for a yearly subscription so I might go for this solution. Thank you for your help!
