Password Security

We recommend that customers use a unique password for their SkyMiles account. Your password on should be 6-20 characters long; cannot be the same as your SkyMiles number, email address or username; and cannot contain any special characters or non-English characters.

Customers should use their SkyMiles number or username and password to logon to

We would like to remind customers that if they use the same username and password combination for multiple accounts at multiple institutions, the risk of unauthorized access to accounts is increased.

If you notice unusual activity on your account, please contact Delta at 800-221-1212. We also recommend that you change your SkyMiles account password immediately and monitor your account for any misuse if you believe someone other than yourself has access to this information.
