Great PM App! I had tried many serious Password Managers, both online and offline based; I bought some of them for different purposes, and I found One Key Pro is the most intuitive by far with great UI & UX and adequate features. • Hopefully this App will continuously be developed for improvements and more features and get regular updates to be more compatible with the last Android version and to comply with Google's latest policies and Phone Vendor's latest updated systems as well. • Thank You

been using this for years but one thing I wish they have is a way to retrieve our master password/ pin through a paid service if we forget if they are concern about people hacking our account with these master password then make it a paid service with strict ID verification and picture verification. I lost 100s of my password on a previous account with them and has started over. if it wasn't because of that experience, this app is the best app out there without any subscription or hidden agendas

My original review was 11-12-2020. I still use One Key daily. I trust it cause it's not synced and stored on a server i dont trust. Although it would be nice if multiple One Key apps could share the same database file stored on my own encrypted storage drive. Another option is trusting a provider like Proton Drive as a host for the live database file. These options would make possible Windows & macOS versions of the app, which would be amazing. Thanks for making the last 5yrs just a bit easier!
