If you are a Microsoft OneDrive user on an iPhone or iPad, then there are interesting new features for the app that you will find in the current update to version 13.13.2.
When creating a new account, you can now also store your cell phone number so that from now on you only need to enter your number for secure registration and a one-time password will then be sent there.
This eliminates the need to remember a fixed password for logging in, which ideally should also be changed regularly.
