macOS ssh can't connect to a Linux VM

I have a Linux VM (Fedora 39 Xfce Spin) created by Parallels Desktop on my Mac, I want to connect to this VM using ssh. But when I tried ssh in Terminal.app, ssh requires my VM's password again and again, even though I've entered the correct password of my VM:

% ssh vmuser@<vm-addr>
(vmuser@<vm-addr>) Password:
(vmuser@<vm-addr>) Password:
......

More Details:

On my Mac: System Preferences > Sharing > Remote Login is on.
On my Linux VM: `PasswordAuthentication yes` in `/etc/ssh/sshd_config`.

Does the password include any accented or special characters? One possibility is that the keyboard layout of the Linux VM is not exactly identical to the one in macOS.

I'd try making a test user with a simple password like "abc" and see if that logs in.

FWIW, you are doing ssh from your mac to the VM, so having Remote Login on or off is immaterial.

Try 2 tests.

1 is an ssh to a known good system

1 is to your VM

ssh -v -v -v user@good.system.address

ssh -v -v -v vmuser@<vm-addr>

Now compare the verbose output from each. They should be similar right up until the VM rejects your password and prompts again. What is different between the verbose VM output and the known good ssh output. There should be a clue about why your password is being rejected.
