None of Bitwarden, 1password, 10+ ‘kee’ apps, MS/Google auth, etc. And I've used a lot of them - none of them came close to Strongbox.

I have a lot of miles on Strongbox and can’t emphasize it enough: this is the best password manager I have ever used. I would highly recommend to my family and friends. Do yourself a favor and grab the Pro version, and support this wonderful developer! Being open-sourced, vetted, and safe is important to me, and this app checks all these boxes. I cannot express how impressed I am with this app, it's the level of functionality and features that reminds me of Android's KeePass2Android, but even superior. Sure enough, not only did it support Argon2 encryption, but it offered a whole host of nitfy features that MiniKeePass lacked, such as FaceID unlock (humongous game-changer in saving time from punching in passwords), easily visible TOTP token keys that you can copy & paste, and also Favicons that are preserved.

Luckily, I searched on Reddit's /r/KeePass subreddit, and found this app was on the list of official recommendations for iOS. Originally a MiniKeePass user, it started to fail me when I was locked out of my own database because MiniKeePass did not support Argon2 encryption algorithm. As a KeePass power user (over 900 entries), I am on the prowl for the most safe, user-friendly, and reliable KeePass app on iOS.
