How to make 100 different passwords for proxy access in squid3?

Question

Squid

Hello, there are 100 ipv6 proxies, they all work, I would like to make one user and 100 different passwords to access specific proxies or a group of proxies, that is, let's say it was like this:
ip: port1: login: password1 ip: port2 :login:password2 ... ip:port100:login:password100
Is it possible to do this? I raise a proxy through 6to4 tunneling, at the moment the proxy is in the ip:port format - without authorization.
