Forgot your Portainer admin password? Learn how to use a handy tool to help you reset it with a tutorial from Jack Wallen.
If you’ve forgotten your Portainer admin password, you won’t have to redeploy the platform because there’s a handy tool to help you reset it. The tool in question comes by way of a Docker container, created by Portainer, for this very task. Let me show you how it’s done.
The first thing you must do is stop the running container. Log into your server, and locate the Portainer ID with the command:
docker ps.
You should see a listing for Portainer with an associated ID. Stop that container with:
docker stop ID
Where ID is the first four characters of the Portainer ID.
Next, you must pull the image designed to reset the password with the command:
docker pull portainer/helper-reset-password
Once the image has pulled, reset the password with the command:
docker run --rm -v portainer_data:/data portainer/helper-reset-password
After the command completes, you’ll see in the output a new password to use for the admin login. Copy that password and restart the Portainer container with:
docker start ID
Where ID is the first four digits of the container ID.
Paste the copied password into the Portainer prompt, and you’re good to go. You can change the password back to whatever you need by clicking your profile icon | My Account and then resetting it as needed.
