Hi there, BruhZilla1!
Thanks for visiting the Apple Support Communities. It sounds like you're being asked to enter your Apple ID and password to update apps. When you do, you get an error that the Apple ID or password is incorrect. I'm happy to help!
It sounds like you may be being asked to sign into a different Apple ID than the one you're trying to use. This can happen if you changed the Apple ID you use on your device, but do not delete and redownload the apps you obtained with the previous Apple ID. Since apps are tied to the Apple ID initially used to download them, they will also require that Apple ID and password to be used to update them.
To solve this, try offloading the apps and redownloading them: How to check the storage on your iPhone, iPad, and iPod touch - Apple Support.
If that doesn't work, delete the app: How to delete apps on your iPhone, iPad, and iPod touch - Apple Support and reinstall it: Redownload apps, music, movies, TV shows, and books - Apple Support.
If you're still experiencing trouble after that, or are having a different issue, don't hesitate to respond back.
Best!
