Can't log in to accounts /apps that work on my ipad

[yesss88ss]

when I try to use my S21 to log in to my accounts / apps I am prompted to reset passwords bc it says wrong password was entered. I already know that they work on my ipad and I also know that changing the password does not fix the problem. this means if I am away from home, I cant use accounts/apps. I am not sure if this is a phone or service provider problem but either way it makes having this phone a distressing thing. does anyone know how to fix this???

@yesss88ss Are you referring to your Apple email, iCloud, etc? 

To use these items on a non-Apple device:

1. Sign in to appleid.apple.com.
2. In the Sign-In and Security section, select App-Specific Passwords.
3. Select Generate an app-specific password or select the Add button, then follow the steps on the screen.
