When users login with EGO, EGO fetches passport from brokers
EGO parses passports
EGO validates the Visas stamped on the passports
how it works: each visa has a public key url that's assigned by the visa issuer. After ego gets the visas, it talks to the visa issuers and get the public keys from them, ego then checks if the public key matches with the one on the visa.
