I'm using a pixel 6 and want to disconnect from all the big providers as much as possible, and GrapheneOS looks like a good option. I'm tempted to jump in the deep end which means wiping the phone and starting again.

Backing up photos should be done, I sync with Immich so that should be ok. Most apps don't really matter about being wiped, reinstalled (if possible) and logging in again. I need to make sure the KeePass file is backed up, and need to check how to preserve the settings from my 2FA app, this is currently using Okta Verify, but hopefully can add the same settings/keys in a FOSS app? Is this easy or should I make sure to roll over the 2FA keys first while I have access?

Bank apps may or may not work but can cross that bridge later, using web only is also possible.

The other tricky thing is the Microsoft apps, currently I'm using some company portal apps for basic work stuff (teams, outlook) and they are very useful and hard to substitute. Has anyone tried these in GOS? I suspect this may not be possible.

Anything else to watch out for?

Thanks
