Every so often I stage a fake 'I lost all of my passwords' desperation recovery on all of the secured products I use. I even offer to pay for recovery. Tutanota a year or so ago provided a method. I cannot disclose that method here because I don't want to legally compromise myself and I am unsure if that method even exists anymore.. However I will merely state they had a way for me to regain access with a full password loss.. A major password product vendor (not bit warden or lastpass), actually offered a recovery method that was rather interesting. If I had a copy of the Appdata folder of the computer that had it installed on backed up somewhere they were able to fully backdoor me into the product. Bit Warden told me to take a hike and that my account was gone forever, which is why I still use them.
I like Tutanota as a general rule, but I do not fully trust them but to be honest I do not fully trust ANY email provider. So I still use Tutanota, despite all of that. But I do seek an alternative I feel more comfortable with that doesn't cost me to much.
