What’s new

Version 10.3.3 · Updated September 24, 2026

What's new? Improvements • Ask Siri for a code, build one into a Shortcut, or add a Control Center button (iOS 18 and later) that copies a chosen account's code from any screen. Everything stays behind Face ID, so a locked phone never gives up a code • Give each folder its own colour, shown in the header, the folder list and account details • Select several accounts at once and file them into a folder in one go, instead of opening them one at a time • Improved Backup UI • A new welcome, and a smarter empty screen Fixes • Syncing no longer merges two separate accounts that happen to share a key • Error and warning messages no longer appear as invisible black text on dark themes • The refresh button on counter-based accounts is much easier to tap • Faster launch, and a far quicker Backups screen if you have a lot saved
