Hi Dominik Frey - Thanks for reaching out over Q&A Forum
To answer for your suggested options:
- Can I set IAM permissions that would restrict users to do so? - No, these permissions aren't controlled via Access Control IAM.
- Can I set a lock on the password? - Unfortunately, this isn't possible as well
- Can I set the password manually, so in case someone resets it, I just simply set it by myself again? - Sorry, you can't have custom password set from your side.
Overall, there doesn't appear to be any option to control reset options other than exercising caution. Let me review it once again and shall update if there is any feasibility of the same.
In the meantime, please let us know if you have any further queries. I’m happy to assist you further.
