I’ve used the app for years, across several versions, and across many devices. I use it on my laptops, phone, & tablet. It is BY FAR the single-most useful and versatile 2FA authenticator application on the market!! I use it every day and I love it. Feature package and ease of use is unparalleled. I cannot recommend it highly enough to anyone who needs a good, effective way to manage their OTP and 2FA accounts in an organised and easy to use app!
