Project description:
"I’m creating a university thesis in computer engineering and need a small-scale yet fully functional secure login module for an educational portal. The core requirements are:

• Standard username/password login protected with hashed and salted credentials.
• Two-factor authentication triggered after successful password entry, offering Email verification and SMS verification as the second step.
• Clean, well-commented code (PHP, Python, or Node.js—whichever you prefer) plus SQL scripts for the user table.
• A concise README that explains setup, configuration of the mail/SMS gateways, and how to plug the module into a typical web app.

Keep the scope lean—just the essentials for a demonstrable prototype. If you can suggest an authenticator-app option, note it separately for future expansion, but focus your build on the email and SMS flows above.

I’ll test by installing on a local server and confirming:
1. Account creation, login, and session management work reliably.
2. Verification codes arrive promptly via email and SMS.
3. Failed or expired codes block access as expected.

Please let me know your preferred tech stack and estimated timeline." (client-provided description)
