Made by the Netherlands’ top app developers at Pixplicity, this app generates single-use password codes that you use in combination with a regular username and password. Much like other well known authenticator apps that shan't be named (and fully compatible!) it works with many online accounts and even without a data connection, but with many, many improvements:
Using this app you can finally back-up your accounts to your favourite cloud, transfer them to a new phone without hiccups, or even share them with your partner.
Only with Pixplicity Authenticator, you..
 • ... will never again have to reset TFA on all your accounts when you buy a new phone.
 • ... won’t have to trust our cloud with your accounts (since we don’t have a cloud and we don’t store your accounts).
 • ... won’t have to trust other cloud providers with your accounts (since we encrypt your back-up using strong AES 256-bit encryption).
Novelty features include:
 • Dark theme support
 • Recognise accounts by their app icons
 • Copy one-time passcodes to clipboard
 • Back-up and restore your accounts
 • Share accounts by scanning a QR code
 • Authorise using your fingerprint before sharing or creating back-ups
 • Encrypted account storage
 • Security: this app doesn't even request internet permission, and is utterly unable to secretly send your stuff to some shady servers.
