[Verse 1] When users knock upon your server door They claim to be someone you've seen before But digital whispers can deceive and lie So check their credentials before you reply A username paired with secret phrase The first small step in security's maze [Chorus] Auth-en-ti-cate, verify who they claim to be O-A-U-T-H, delegate authority J-W-T tokens carry claims inside Session cookies where the secrets hide Trust but verify, that's the golden key Authentication sets your users free [Verse 2] OAuth flows like a trusted friend Who vouches when you need to lend Your service asks another site "Is this user genuine and right?" Google Facebook Microsoft agree "Yes this person's known to me" [Chorus] Auth-en-ti-cate, verify who they claim to be O-A-U-T-H, delegate authority J-W-T tokens carry claims inside Session cookies where the secrets hide Trust but verify, that's the golden key Authentication sets your users free [Bridge] Hash those passwords with some salt Never store them plain, that's a vault default Sessions timeout, tokens expire Refresh mechanisms when access gets dire Multi-factor adds another layer Security depth makes hackers prayer [Verse 3] JSON Web Tokens signed with care Header payload signature there Stateless verification on every call No database lookups after all But sessions stored upon your server Give you control, a fine preserver [Chorus] Auth-en-ti-cate, verify who they claim to be O-A-U-T-H, delegate authority J-W-T tokens carry claims inside Session cookies where the secrets hide Trust but verify, that's the golden key Authentication sets your users free [Outro] Secure HTTP only flags CSRF tokens in your bags Login systems built with thought Keep the bad guys out, let good ones through the spot
