[personal settings] Move "Change password" to "Security"-settings

[MariusBluem]

I think a password is not related to "Personal information" but more to "Security". We could add it as a section there. It should be clear, that this is a special kind of data - not like your twitter profile name :D

@juliushaertl @skjnldsv Does one of you want to look into this?

[juliusknorr]

Yes, makes sense to me. I will have a look into that.

@nextcloud/designers Does this still make sense? I think this is a nice and small polishing part that could still be done for 14.
