SSH Permission denied (publickey) on Raspberry Pi
0
I used to be able to establish a ssh connection to my Raspberry Pi but suddenly it failed on me.
The usual way to log in is just
ssh pi@192.168.0.140
and it would request a password.
But today when I come back from work, suddenly it denied my access and it won't even ask for a password. Pretty sure no one mess with my Raspberry Pi as it is stored in a very secure location, my family members will not and have no intention of using it.
Note:
- Checked with the connection, port is available to access
- I have tried to start fresh by removing the
known_hostfile and regenerate the key to no avail.
Here's the error log

Was able to get a monitor and access the /etc/ssh/sshd_config file.
Found the culprit,
PasswordAuthentication no
Changed to yes and I am able to connect again.
