Login vs. Signup: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on February 11, 2024
Login is the process of accessing an existing account, while signup is the process of creating a new account on a platform or service.

Key Differences

Login is used to access an existing account using credentials like username and password. Signup is the initial process of creating a new account, often requiring personal details and email verification.
Users login multiple times after account creation, using the same credentials each time. Signup is a one-time process unless creating multiple accounts.
During login, security measures like two-factor authentication may be involved. Signup may include captcha verification and acceptance of terms and conditions.
Logging in is a quick process for returning users. Signup involves filling out a form and is usually followed by an account confirmation step.
Login typically requires just a username and password. Signup asks for more information, such as email, password, and sometimes additional personal details.
