LinuxMint 20.3: Enter the Login Keyring password via the command line

Question

#Refer: How to enter the Default Keyring password via the command line? - Ask Ubuntu

I am asking this question here as I am not using Ubuntu and also the solution mentioned there doesn't work in LinuxMint 20.3

---

$ whoami
nikhil
pip install keyring

I created an executable python script as follows:

import keyring
import getpass

keyring.set_password('login', 'nikhil', getpass.getpass('Password: '));

On executing the script and entering the password, the Login keyring still remains locked. Any suggestions?
