If you have 2FA set up for many accounts like I do, it gets to be a pain scrolling through that list to find the one you want. Categories to the rescue! From the settings menu go to manage categories, from there you can create new categories and put authenticators in them.
Categories in Authenticator Plus work more like tags than folders, you can put one authenticator in as many categories as you want. Sorry readers, that was a lie. The interface is kind of confusing, so I thought categories worked like tags, but they are actually folders. Either way they’re still really useful. Once you have your categories set up, you can switch between them from the hamburger menu. The categories list is at the top where it’s easy to find.
Now that I have my authenticators sorted into work and personal categories, it’s so much easier to find the one I want.
