Seems to be fixed in 7.20.1
Thanks for letting us know!
What I find pretty scary is that apparently Mendix added/changed a password strength check, but this change itself is not documented in the release notes at all. Imo, if there is a change, it should be mentioned in the releases notes...
Thank you Andrej!
Thanks, would be nice if they would inform the users a little bit more proactively (for example by sending an e-mail).
Is the problem fixed since 7.20.1?
