The "external" ACL type runs a (or several) helper programs on
persistent connections which perform arbitrary out-of-band operations
and return to Squid the authorization approval to allow/deny the
transaction.

There is Negotiate authentication. The security tokens are setup
out-of-band and used securely in-band.

I also have a patch implementing OAuth 2.0 Bearer authentication for
Squid. Although it needs some polishing and clients supporting
proxy-auth Bearer seem to be a rarity still. Sponsorship welcome to
get those final steps completed.
