10 1Password

1Password is one of the best and most secure password management tools for iOS. It saves all of your login details in one place and syncs them across all of your connected macOS and iOS devices. The best feature of 1Password is that it can enter your login details into a web page automatically. All you have to do is to select the login item to be used.

1Password also integrates with Safari so that your login details can be entered automatically. When you’re on a page that has a login form, open the iOS Share Sheet and tap on 1Password. Then select the login item to be used. 1Password will automatically input your username/email and password into the login form. Download: 1Password (Free)
