Managing Your Account

Signing in and resetting your password

Sign in at https://www.aladdinsci.com/us_en/customer/account/login/ (or click Sign In in the site header) with the work email address on your business account and your password. There is one sign-in for everyone on the account — administrators and invited colleagues use the same page.

To reset your password. Click Forgot your password? on the sign-in page, enter your work email and click Reset My Password. The email arrives within a few minutes; the link in it is valid for a limited time . Choose a password of at least eight characters with at least three of: lowercase, uppercase, numbers, special characters. If no email arrives, check your spam folder, confirm you are using the address your administrator registered for you, and try again; the reset form does not reveal whether an address exists, for security.

What to do

The email or password you entered is incorrect.

Either value is wrong, or the account has not been activated yet. The message is the same in both cases on purpose.

Check for typos and Caps Lock, then use Forgot your password?. If you registered recently and have not received an activation email, your application is still under review (What happens after you apply).

The account sign-in was incorrect or your account is disabled temporarily. Please wait and try again later.

 

The account is temporarily locked after repeated failed attempts.

Wait, then sign in or reset the password.
