Reset your password
To reset your password (in case you forgot it, or you still don’t have one) go to the Login page. Enter the email you signed up with and click Next. On the next page click Forgot password and an email with a reset password link will be sent to you.
Click the link and you’ll be taken to a page where you can choose a new password. (Note that if you request multiple password reset emails, the previous email will immediately become invalid.)
If the email doesn't arrive within a short period, don't forget to check your Spam or Junk Mail folder first for the email containing the reset password link.
Change your existing password
To change your existing password, go to Settings > Your Account and scroll to the Change Password section. Passwords must be at least 8 characters long, have at least one lowercase character, one uppercase character, and one number.
Set your mobile/Single Sign-On password
If you are using Gmail, Yahoo, or Google Apps Single Sign-On, you can set and change your Expensify password in Settings > Your Account.
You will need this password to sign into the mobile apps. Also, some mobile phones only allow alpha-numeric passwords, so try resetting your password if you are unable to sign into your mobile.
