Signup and Login


When you launch the Web-UI, login dialog appears. If you haven’t signed up yet, press the SIGN UP button.

Login dialog

Enter the required information, read and agree to the Terms of Service / Privacy Policy, and click the SIGNUP button. Depending on your system settings, you may need to enter an invitation token to sign up. A verification email may be sent to verify that the email is yours. If the verification email is sent, you will need to read the email and click the link inside to pass verification before you can log in with your account.

Signup dialog


Depending on the server configuration and plugin settings, signing up by anonymous user may not be allowed. In that case, please contact administrator of your system.


To prevent malicious users from guessing user’s password, password should be longer than 8 characters with at least one alphabet(s), number(s), and special character(s).


Enter your ID and password and press the LOGIN button. In API ENDPOINT, the URL of Backend.AI Webserver, which relays the request to the Manager, should be entered.


Depending on the installation and setup environment of the Webserver, the endpoint might be pinned and not configurable.


Backend.AI keeps the user’s password securely through a one-way hash. BCrypt, the default password hash of BSD, is used, so even the server admins cannot know the user’s password.

After login, you can check the information of the current resource usage in the Summary tab.

By clicking the icon in the upper-right corner, you will see sub menus. You can logout by selecting the Log Out menu.

When you forgot your password

If you have forgotten your password, you can click the CHANGE PASSWORD button on the login panel to email a link to change password. You can change your password by reading and following the instruction. Depending on the server settings, the password change feature may be disabled. In this case, contact the administrator.

Signout button


This is also a modular feature, so changing password may not be possible in some systems.


If login failure occures more than 10 times consecutively, access to the endpoint is temporarily restricted for 20 minutes for security reasons. If the access restriction continues on more than 20 minutes, please contact your system administrator.
