"Auth" is also super overloaded. OP is an authentication or AuthN tool which is not the same nor does it encompass authorization or AuthZ. I'm partial to using the terms "identity" and "permissions" instead.
I'm in total agreement with you but I guess the AuthN/AuthZ train left the station ages ago and no one outside of the business of selling these tools actually care. Oh well.. :o)
it used to be called authenticator! mixed it up unintentionally
