If a single person regularly uses many services like mastodon, pixelfed & peertube, could there be a way for that person to use a single account/identity to interact with all these platforms.
So that when that person likes a peertube video, the uploader gets a notification from email@example.com, and when they interact on pixelfed they interact from the same identity.
Instead of the person having to use firstname.lastname@example.org & email@example.com to interact with these platforms.
Is such a thing possible?
Could posts / media / interactions all be attributed to a single handle?
