Telekom recently switched their MagentaCLOUD service to a new system. Steganos Password Manager 22 has received the necessary adjustments for this and the synchronization of passwords with MagentaCLOUD is possible again.
If you are using an older version of Steganos Password Manager, you can either upgrade to the current version or switch to one of the other cloud services to synchronize your passwords. Since the keychains are always encrypted locally before being uploaded to the cloud, the provider used is not relevant for the security of the keychain. The prerequisite, of course, is that you use a master password that is as strong as possible.
