User Authentication Flow: an editable mindmap
Explore User Authentication Flow as an editable mindmap. Follow color-coded branches for Register, Sign in, Session, Protected requests, Failure path, with supporting ideas and curved connections.
A mindmap of User Authentication Flow, with the main ideas arranged around a central topic and connections that show how they relate.
User Authentication Flow: an editable mindmap
The interactive MindMap canvas for this explanation — every lane, row and arrow above is a real QueryChart diagram you can open and edit.
How to read this mindmap
- Begin at “User Authentication Flow” in the centre, then explore any branch that answers your question. The branch colors keep each group of ideas together.
- Curved lines show relationships; arrowheads appear only where one idea leads to another. Select any idea in the editor to change its text, position, or connections.
Register
This branch brings together “User creates an account”, “The password is salted and hashed before it is ever stored — the service cannot recover the plaintext, and a leaked database does not leak credentials.”, “Hashed credential is stored in the database”, “Client sends email and password”.
Sign in
This branch brings together “User signs in with credentials”, “Client forwards them to the auth service”, “Hash matches the stored one?”.
Session
This branch brings together “Auth service creates a session”, “Client stores the session token”.
Protected requests
This branch brings together “The token proves the session without re-entering the password. Multi-factor authentication inserts a second check at sign-in when the risk profile demands it.”, “Access granted for the session”.
Failure path
This branch brings together “Sign-in denied”.
Connections across the map
Passwords are hashed before storage: the database holds a salted one-way hash, never the plaintext.
Sign-in compares hashes, so the auth service itself cannot recover the stored password.
The session token replaces the password for subsequent requests, which is what makes authentication practical at scale.
Storage and verification are separate concerns in different lanes, so each can be protected separately.
The flow is the same shape whether the token is a server session or a JWT: see the JWT visual for the token mechanics.
Key relationships and takeaways
- Passwords are hashed before storage: the database holds a salted one-way hash, never the plaintext.
- Sign-in compares hashes, so the auth service itself cannot recover the stored password.
- The session token replaces the password for subsequent requests, which is what makes authentication practical at scale.

- The flow is the same shape whether the token is a server session or a JWT: see the JWT visual for the token mechanics.
When to use this visual
- Teaching a new team the secure shape of authentication before they design their first sign-in.
- Reviewing an auth flow for the classic flaws: storing plaintext, comparing plaintext, trusting the client.
- Grounding a conversation about multi-factor authentication and where it plugs into the flow.

Frequently asked questions
What is the secure way to store passwords?
Never store the password itself. Store a salted hash (a one-way function applied to the password plus a random salt) and discard the plaintext. At sign-in, hash the incoming password the same way and compare the hashes. If the database leaks, the attacker gets hashes they cannot reverse, which is exactly the property the visual's hashing boxes exist to show.
What is the difference between hashing and encryption?
Encryption is reversible: with the key you can recover the original value. Hashing is one-way: there is no key and no way back. For passwords you want hashing, because you never need the plaintext again, only the ability to verify. The visual says "hashes" rather than "encrypts" for this reason; encrypting passwords is a common and dangerous confusion.
How does a session token replace the password?
After a successful sign-in the auth service creates a session and hands the client a token (a random value, or a signed JWT) that stands for the authenticated user. Protected requests carry the token, and the server validates it instead of asking for the password again. That is what makes authentication practical for repeated requests, and it is why the token's expiry is the real security boundary.
Where does multi-factor authentication fit in this flow?
MFA is an extra check at sign-in, after the password is verified and before the session is created: the user provides a second factor: a one-time code, an authenticator app, a hardware key. The visual's sign-in column is where that step plugs in. MFA does not change the hashing or session mechanics; it raises the bar on the one decision, "Hash matches the stored one?", by adding a second proof.
