I used to use the MiniKeePass iOS App on my iPhone to store all my passwords, but since that has been discontinued, I have moved over to Strongbox. I have been using the free version for a long time, but decided to pay for the app as part of their Black Friday / Cyber Monday deals (20% off). They are now running another 20% off promo from 29th-31st Jan (US dates).
I prefer Strongbox/KeePass type password managers, as the password file is stored on your device, and not in the Cloud. I used my same database from KeePass and simply imported it into Strongbox.
The free version doesn't allow you to use FaceID/Touch ID and forces you to enter a password every time you want to access your password file. This Pro version unlocks those features and more.
The app also receives constant updates to get new features. e.g. https://strongboxsafe.com/updates/advanced-sync-and-auto-mer...
