What are some good options for this? I think my ideal solution would export an encrypted file, a bit like KeePass does on the desktop, but I don't know of many mobile apps for that.
It has two security levels: normal-level security codes will unlock when the phone is unlocked, high-level security codes require a separate unlock to get the code. The former back up to iCloud (E2E encrypted), the latter don't back up.
