Sign in failed is a catch all message, and in the app it is usually one of four things: a stale session, the wrong app, two step verification not set up, or a password you changed in the portal and not in the app. It is rarely an account problem.
At a glance
Last verified November 10, 2026. Walmart changes these systems often, so if something on screen does not match what you read here, the system changed and this page has not caught up yet.
Work through these four
Why signing out fully matters
The app stores your credentials. After a password change it keeps trying the old ones and keeps failing, which reads as the change not having worked. Closing the app is not the same as signing out of it.
The test that saves the most time
Try signing in to one.walmart.com in a browser. If that works, your account is fine and the problem is the app. If it does not, the problem is your credentials or verification, and the app was never going to work either way.
Full detail is in the nine login fixes and the app guide.
Frequently asked questions
Why does MyWalmart say sign in failed?
Most often a stale session after a password change, the wrong app, or two step verification not being set up for use outside a store.
Do I have the wrong app?
The associate app is MyWalmart, or Me@Sams for Sam’s Club. The Walmart shopping app is for customers and will not show your schedule.
Should I reinstall the app?
Try signing out fully first. Before reinstalling, make sure you can sign in to the portal, because reinstalling needs your credentials.
Why does it work at the store but not at home?
Store devices skip two step verification because they are inside Walmart’s network. From home you have to pass it.
Could my account be locked?
Repeated failed attempts can lock it. Stop retrying and reset the password instead.
