Saying Incorrect Password

[Jack05]

I woke up this morning and went to go onto my phone and it keeps coming up "incorrect password" when I know it is the correct password as it is my baby's name and worked every day till this morning. I am stuck on Maximum Power Mode and can not do anything.

I got the same issue but for wifi. The password for wifi was good but it was telling me it was incorrect. I fixed it by going into the router settings and I switched wifi from wpa2-psk/wpa-psk to wpa2-psk.
