I’m trying to implement a single set of credentials across multiple WordPress installs that sit on the same server but on different domains entirely. e.g. squirrel.com, badger.es, horse.coffee.
I have been looking at auth0 for sharing credentials, but I still need to login using those same shared, valid, credentials on each individual site, where ideally I could visit one of the other sites and be already authenticated.
Is this possible using auth0 or some similar method? Should I be looking at multisite instead?
Any suggestions are welcome. Thank you
