How to add user accounts and login to your site for free

You do not need to build login from scratch or pay for it to start. Managed authentication on free tiers handles sign-up, secure passwords, email confirmation and password reset for thousands of users. The key is to never store passwords yourself and to protect data with access rules — both built in when it's set up properly.

The moment your site needs people to log in — members, students, customers — you need authentication: sign-up, secure passwords, email confirmation, password reset, and sessions that keep people logged in. Building this yourself is risky and slow. The good news is that solid, managed authentication is available free for thousands of users.

What you should never do

Never store passwords in plain text, and never invent your own password scheme. Secure systems store only a one-way, scrambled version of a password that even the operators cannot read. Managed authentication does this correctly by default, which is a large part of why using it beats rolling your own.

What a free auth tier covers

• Sign-up and login with email and password
• Email confirmation and password reset flows
• Secure sessions across devices
• Rules so each user can only read and change their own data

The piece people forget: access rules

Login alone is not security. The real protection is access rules on your data, so that even a logged-in user can only touch their own records. A platform that offers authentication plus row-level access rules gives you both halves — identity and protection — on the free tier.
