Hello, following your unannounced changes of 8th October I have been locked out of my swisscom account which says I need to set up 2fa, I decided to try and make it work and now it wants to scan my id card too.
The scanning failed so now I must wait for a letter.
This combined with some sort of screw up you have made with e-mail access as a result of these changes leads me to believe it was totally unplanned (no advance notice) or planned/implemented by someone who had not done sufficient analysis/planning of what they were doing.
