Synchronization allows software and apps installed on a computer, phone or tablet to access the data of your postel.bzh account: mail, virtual disk, address book, calendar.
No single universal protocol allows the synchronization of all data types. Numerous protocols coexist and each terminal supports one or more of them. postel.bzh supports the main synchronization protocols, which allows you to access your postel.bzh data from most existing software and apps.
For more safety, you can disable the protocols that you do not use, which will block any access attempt. You can also use application passwords instead of the password of your postel.bzh account, in order to control the usage of these protocols.
