Sentinel — Password Manager In short, what does this app do for you? Sentinel keeps all your passwords and subscriptions secure and easily retrievable on your iPhone such as streaming services, email providers, websites, and computer logins. If you lose your phone, you can still retrieve your information from your encrypted iCloud backup. Sentinel also tracks your subscription payment dates so you’re never surprised by a renewal. The app warns you if any of your passwords have been leaked or if your login credentials appear in known data breaches. You can generate unique, super-strong passwords which we highly recommend and the app automatically fills them into login fields for you.
