What Authentication means
Methods include passwords, magic links, passkeys and sign-in with Google or Microsoft. Authentication proves identity; authorization decides what that user is allowed to do.
Why it matters for your website
Most website break-ins start with a weak, reused or stolen password. Strong authentication protects customer data, your admin area and your reputation. Adding a second factor is one of the most effective security steps a small business can take for very little cost.
Example
A tutoring company requires two-factor authentication for every staff account on its website and CRM, so a phished password alone is not enough to log in.
Tips
- Turn on two-factor authentication for every admin and staff account.
- Use a password manager to create unique, long passwords for each service.
- Prefer authenticator apps or security keys over text message codes when possible.
Common mistakes
- Reusing the same password for the website, email and hosting accounts.
- Turning on two-factor only for the owner while other admins log in with just a password.
Questions about Authentication
What is Authentication?
Confirming that a user is who they claim to be, usually at login.
What is the difference between authentication and authorization?
Authentication checks who you are, such as logging in. Authorization decides what you are allowed to do once logged in, such as editing posts or changing settings.
What are passkeys?
Passkeys are a newer sign-in method that uses your device, along with a fingerprint, face scan or PIN, instead of a password. They resist phishing because there is no password to steal.
