I am using Ubuntu 16.04 LTS with Graylog 2.2. I am able to access the login page, but no matter what I set the password to and run it through the command “echo -n password | sha256sum” I cannot log in. I have not been able to find where anyone else has had this issue either. I did go as far as wiping the server clean and starting all over again (it’s a Hyper-v VM), but the exact same issue occurred again. I am not sure what I am doing wrong now. could someone please assist? ---

Try using the SHA-256 hash of “password” (literally…) for testing: ```auto root_password_sha2 = 5e884898da28047151d0e56f8dc6292773603d0d6aabbdd62a11ef721d1542d8 ``` Also, how exactly did you configure Graylog and which error messages do you see in your web browser when trying to log in? ---

I did test it with the password “password” and unfortunately it did not help. The error isn’t actually an error, but just a denied due to bad credentials. The message is “Invalid credentials, please verify them and retry.” The command that I ran was: echo -n password | sha256sum and the outcome was: 5e884898da28047151d0e56f8dc6292773603d0d6aabbdd62a11ef721d1542d8 ---

Using the hash for “password” (`5e884898da28047151d0e56f8dc6292773603d0d6aabbdd62a11ef721d1542d8`), how does your Graylog configuration file look like? ---

It is going to be a few minutes because somehow I just accidentally cleared the server.config file while attempting to output it to screen so that I could copy and paste it here. ---

I wiped out the server and set it back up with no issue logging in now. Sorry, I do not have a solution other than that. ---

Your password secret is incorrect. The secret isn’t supposed to be a sha256 hash, it’s supposed to be in the form of command options. > password\_secret > You must set a secret that is used for password encryption and salting here. The server will refuse to start if it’s not set. Generate a secret with for example pwgen -N 1 -s 96. If you run multiple graylog-server nodes, make sure you use the same password\_secret for all of them!
