The design is clean and modern and the app runs very smooth. It's also easy to use. I switched from Google Authenticator because I was having serious lagging issues and crashes. Backing up my codes in an encrypted, hidden, and password protected file on Google Drive is genius. I never have to worry about my phone being lost, stolen, or decommissioned. I would highly recommend this app.

Easy enough to use. I don't necessarily need biometrics or a pin to access the codes though because I already have to do biometrics or type in pins for the app I'm signing into with 2FA and a password manager, and it's a little frustrating to switch between them. It would be nice to have the option to enable them when editing any of the settings. Unfortunately, it's an all or nothing affair. Edit: I mean disable them for getting the one time codes, but enabled to access the service keys.

Hi Miguel! There is a possibility to switch off pin and biometric ID. You just go to Settings and then choose Pin Lock and Fingerprint Lock. What's more, we're currently working on widgets that will allow an easier and faster access to your tokens. Hope we helped 😊

Used only for a few minutes to secure some of my sites and it seems to be working well! It's got fingerprint (or pin) protection, sync to google drive (with password), plus export to local file (with password). EDIT: A minor annoyance with the latest update (which I complained about) got fixed within 24 hours, pretty impressive! 👍
