Kyocera's New Rugged Flip Phone is Washable

I got this phone about three weeks ago and I cannot establish connections to any of my three email accounts: yahoo, gmail, comcast. I go through the procedure and get the response that the name or password is wrong. I am using these accounts on three computers via direct internet or Windows 10/11 mail client. No problems. All accounts are one level security, a simple password. I cannot access the accounts using the browser in the Kyocera either.

Is there some security setting in the phone that could be causing the problem? Any help would be appreciated.

I wish the phone would be able to run Google Play Store & Services (it hadn't worked on my phone so far; whenever I try opening them the phone says "Google Play Store/Services keeps stopping" and it doesn't open). Every other app that I downloaded on my phone worked; why won't these?
P.S. If anyone has a solution to make them work, pls reply here.

This is a nice phone.

I wish these types of phones were out 15-20 years ago with the soft/hardware they have on them now.
