Rhanks for this update! Good learning points. The advise of regularly changing your passwords is not promoted anymore by the big tech companies. Setting long, random and different passwords for your accounts still is a good practice. Configuring MFA and/or pass keys is also recommended.

And as you mentioned already; checking permissions.
It's also wise to review the rights you've given for any Hive apps to post on your behalf every now and then by the way.
