G4 keeps asking for email passwords?

[Cuerte]

I have 2 Yahoo email addresses linked to my Email app on my Verizon LG G4, 6.0.1, and it always tells me that "The password on the account has changed" for both accounts, and that i must enter a new one, even when I didn't change the password. The weird thing is, if I ignore the message, the email accounts still update and retrieve my emails regardless. Its super annoying that this keeps happening and i don't know why it is.
