If you log in to Smartsheet using a password that doesn't match what's set up on your account, you'll see the following error message:
Invalid email address or password. If you do not have an account, click the Sign up link below.
If you exceed the number of login attempts and aren't successfully able to log in, you'll be locked out of the account and won't be able to log in even if the correct password is used. To unlock the account, you'll need to reset the password at https://app.smartsheet.com/b/pwd.
Follow the instructions on screen and you'll receive an email with a link you can use to create a new password for your Smartsheet account. We recommend copying the link in the email, pasting it into your browser's address bar at the top, then pressing [Enter] or [Return] on your keyboard to access the password reset link. You'll be directed to a screen where you can enter a new password, confirm the new password, then continue to access your Smartsheet account.
NOTE: Passwords must be at least 6 characters long.
If the password reset link received via email is truncated, or additional characters are appended to it, this will invalidate the link and display the following error message:
Unable to automatically sign you in - please enter your email address and password.
Certain programs such as McAfee Click Protect and Barracuda Email Services can cause this type of interference with links you receive via email. To resolve this permanently, ask your IT department to add *smartsheet.com* (including the asterisks) to all exception lists in the email protection service. More detailed instructions are available in the McAfee Support Center or the Barracuda Support Center.
In the meantime, contact Smartsheet Support for assistance with signing in to your account.
