Cash App Unable to Sign in on This Device – Reasons and Solutions

To resolve the “unable to sign in on this device” issue, we have to first find out why the message appeared in the first place. 

This isn’t an easy task and should be accomplished using the trial and error method. That way, we’ll be eliminating potential issues until we (hopefully) get to the bottom of the issue.

1. Update Cash App

If you don’t have automatic app updates enabled, there’s a great chance that your Cash App has become outdated and you should update it in order to continue using it. 

To do that, simply connect to WiFi and go to your phone’s app store. Here you can search for Cash App and tap update, if available. 

If your app is up to date, there will be no option to update it and that isn’t the underlying issue that forced the appearance of the “unable to sign in on this device” message. 

2. Check Network Connection

Some apps can be nitpicking and in need of a stable and safe internet connection. That rules out almost all public networks (hotspots) and some mobile networks, especially when the connection is slow, isn’t strong enough, and it’s often breaking up.

In such cases, you should try and connect to your usual network, i.e., your home WiFi. You could also reposition to a place where the mobile network is more stable.

3. Sign Out of Other Devices

This is a common thing that we do nowadays. We log into the same app, in this case, the Cash App from different devices (laptop, smartphone, another smartphone…) and forget to log out.

This can trigger Cash App into thinking that someone else, not us, is trying to log into our account. For that reason, the app might not let you log in on the current device until you sign out of all your other devices.

4. Turn Off VPN

VPN is a necessity for some people. That includes everyone connecting to public WiFi. It’s notorious for being unprotected and your sensitive data could be shared with others. 

College students, university faculty, office workers, and many others that want to freely access the internet while connected to their institution’s WiFi are also included here. 

But VPN doesn’t work at times with Cash App. Especially if you have the VPN set up to connect to a country outside of the US or the UK. These are the only countries where Cash App can work. 

Try turning off your VPN, if you’re using it at the same time as Cash App. 

5. Server Issues

At times, the backend of the app might not work as intended. There could be many reasons for that happening, but usually, it’s an issue with some of the servers not working properly. 

This can lead to service outages, however, they are usually resolved very quickly. Nevertheless, if you’re trying to sign in at that exact time, you might experience the “unable to sign in on this device” message. 

There’s nothing much you can do in that case. Check the Cash App status page to see if everything is green and wait for it to be resolved.

6. Check For Malware And Viruses

Although cell phones aren’t prone to malware and viruses, Android phones could have an issue with them. Simply download an antivirus and malware checker to see if your phone is plagued with malicious software. 

But beware, some of these antivirus apps can do more harm than good. They can drain the battery and even install their own trackers. Choose a reputable app.

7. Reboot the Device

One of the better and more simple solutions to the “unable to sign in on this device” issue is to simply reboot your phone and try again. This classic advice does truly help with many issues that can arise on smartphones and computers alike. 

8. Re-Install the Cash App

It’s easy to re-install the app. All you need to do is to: 

  1. Go into your phone’s settings
  2. Tap on “Apps”
  3. Tap on “Manage Apps”
  4. Search or find the Cash App
  5. Tap on “Clear data”
  6. Tap on “Clear cache”

  8. Tap on “Uninstall” 
  9. Open App Store
  10. Install Cash App
  11. Enter login details
  12. Connect your bank account or card again

9. Try Signing in on a Web Browser

If you want to exclude issues on Cash App’s side, try logging in through a web browser. You don’t have to use a laptop to do that, just open up your smartphone’s browser. 

However, if the mobile browser is persistent in pushing you to use the app, you might need a computer to do this.
