Lyrics

[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
