Amazing App

All your 2fa codes are synced with all devices, even the Apple Watch. Best free app to make your accounts more secure.

Good App. Solid Devs.

I have never written a review before, but I think this app has potential to really be great.

Right now, it is just *good* but the cross device synchronization and aesthetics of the app are great.

Emailed the developer a feature request and they responded within 24 hours saying they will add it to the next release!

Once this app lets you add custom labels, and re-arrange the order, it will be 5 stars for sure.
