Security & Session Management Flow
Understand the core mechanics, queues, and logic routines running on our servers when processing this module.
System Execution Pipeline
Below is the step-by-step sequence of events executed by our background workers.
User Authenticates
User inputs credentials. Passwords are evaluated against stored bcrypt hashes.
Token Generation
On match, the server generates a JWT containing the user identity, signed with a secret key.
Route Guards
For every dashboard request, Next.js middleware verifies the token signature and expiration.
Session Close
When the user clicks logout, the token is saved in a Redis blacklist store, blocking future uses.
Developer & Architect Notes
Technical Architecture
This module operates as a stateless service hosted across horizontally scalable server nodes. Distributed state coordinates through highly optimized Redis transactions to ensure consistency without deadlocks.
Edge Fail-Safe Rules
Critical protocols (like connection failure retries, cool-down timers, and data limits) are verified before outbound dispatches. Failures degrade gracefully, prioritizing list health and preventing blacklisting.
How security & session management behaves.
Answers about the execution flow, failure handling and limits of this module.
How are account passwords stored?
Passwords are hashed, never stored in a form that can be reversed. Nobody at Email.biz.pk can read your password, and a password reset issues a fresh cryptographic token rather than mailing you the existing one.
What happens to my active sessions when I change my password?
Existing session tokens are added to a blacklist and rejected immediately, so a password change or a sign-out genuinely ends every other session rather than leaving old tokens valid until they expire.
Do password reset links expire?
Yes. Reset tokens are single-use and time-limited, so an old reset email cannot be used to take over an account later.
