Changed account password - how to change in Software?

Hi together,

some weeks ago I changed my Acronis Online password. Now I recognized that my local Acronis Online Backup installation does not backup anymore (well, that is what I expected). But I did not find out where to change my password in the Acronis Online Backup Software. Can you help me?

And one more question: when changing password, is it necessary to upload all data again or is it possible to "continue" Backup?

Thanks in advance!

Greetings,

Tobias
