Here is what I am getting with debug.

Can you please tell where is the wrong password coming from?

Hi, you need to check your username and passwords on both routers.

router A

username B password cisco

Router B

username A password cisco

That should do it.

the router received incoming failure, so remote router fail the authentication.

This is a password mismatch for sure

If you notice the I and O which represents the input and output respectively, so either "kwepdx" is senting a wrong password or "rt706a" is configured with the wrong password.
