Having multiple accounts on different homeservers is preferable for many reasons such as ensuring decentralisation of power and being able to manage rooms from multiple places even with federation meltdown.
* matrix:u/mikaela.suomalainen:matrix.org - professional context where shouldersurfing may be a concern. Also Element-{X,Android,iOS}. (Predates my December 2021 namechange a bit)
* matrix:u/aminda:beeper.com - Beeper is building everything on top of Matrix while having their own clients and everything, so thus it will likely be on all my devices and sending notifications, regardless of any primary status of the account.
These accounts are deactivated and thus no longer usable by anyone. If they reappear, assume malicious homeserver and ACL on sight.
* matrix:u/aminda:the-apothecary.club - used to exist for accessibility testing animated avatars e.g. https://github.com/vector-im/element-web/issues/18442 and https://github.com/vector-im/hydrogen-web/issues/841 . I disagree with how they run their communities and thus have deactivated the account myself.
