Your Costco account holds your membership, your orders, and the card and address you use to shop online. If someone gets in, they can order on your card and see your personal details, so the login is worth guarding. Our GetMyPassword team explains how to change your Costco password, reset it when you are locked out, and keep the account secure.
Change your password in account settings
- Sign in at costco.com or in the Costco app.
- Open your Account, then sign-in or security settings.
- Select change password.
- Enter your current password, then a strong new one, and save.
Use a long password you do not reuse anywhere else, so a leak on another site cannot open your Costco account.
Reset a forgotten password
On the sign-in page choose Forgot password? and enter your email. Costco sends a reset link; open it and create a new password. Keep your email account secure, because anyone who controls it can reset your Costco login as well.
Protect your membership and card
Your account ties to your membership and a saved card, both worth protecting. Turn on any two-step verification Costco offers, and watch for phishing: emails about a “membership renewal,” an “order problem” or a “reward,” pushing you to log in or pay through a link, are a common trick. Open the site or app yourself instead of tapping the link.
A “renew your membership now” email with a convenient link is a classic lure. Real renewals can wait until you open the site yourself — a fake one is counting on you not to.
Lock it down with a generated password
Create a long, random password for Costco with our password generator and keep it in a password manager. With two-step verification and the habit of never logging in through email links, your membership, orders and card stay protected.
