I cannot login to my user directly from SSH, `Permission denied (publickey).`.
Hello I have been using DigitalOcean for couple of months for my Python Flask project. I usually starts my Droplet creation with these commands.
# In my local computer. ssh email@example.com # In droplet. adduser user_test usermod -aG sudo user_test su - user_test # Logged in into user user_test.
I used DigitalOcean since last year November and then stopped using DigitalOcean for the last two months. I am pretty sure after the commands above I can directly connect into user user_test with this command.
However today login with such command now results in
Permission denied (publickey).. If I want to login into user_test I need to login from root.
ssh firstname.lastname@example.org su - user_test
Is there any steps I missed those make me unable login directly to user?
