I would recommend using a password manager that keeps track of every change you made to the each entry, enable it for protonmail or at least write it down on the notes section whenever you make a password change.
I manage to lose some data on protonmail over this since previous email are not recoverable when you forcefully change your password. Silly mistake on my part? Maybe, but I do use KeePassXC to handle all my passwords and tried each and every one on the history and still wasn't able to recover those emails.
Which is why I'm very wary of Protonmail as well. I still use them but make sure that anything sensitive is properly backed up elsewhere before making any changes to the password. I also like Tutanota quite a bit.
OK that was a migration problem. The only thing that affected me was corruption to the Zorin manual I created which was rectified. I can't see issues with murena as it is headed by the founder of Mandrake Linux and Ulteo.
Alleged data leak when there wasn't one, by that not a hack but a scripting error when moving to new platform. As stated in Gael's notice, less than 5% of users affected and only for 15 minutes. The migration took place in just over 1 day, pretty good when others on the e.community.forum mentioned other platforms taking over a week for successful migration.
It was originally the e.foundation. selling smart phones that are un-Googled. I have the Fairphone 3+ made from 100% material. They also have the OS to install to other phones.
I installed e.OS on an old 1+ 3. No need to upgrade as comes with removable battery, and you are provided with a mini Philips screwdriver so you can replace any module should it get damaged. You can even replace the screen yourself.
At the time I purchased I signed up for free @e.email address and 1 Gb of free cloud storage.
But you don't need a smartphone to get murena account:
