TL;DRTo activate the 1Password ngrok shell plugin:
  1. Sign up for 1Password
  2. Install and sign in to 1Password on your machine
  3. Install the 1Password CLI on your machine
  4. Integrate the 1Password CLI with the 1Password desktop app
  5. Import your ngrok credentials into 1Password
  6. Launch ngrok
This guide covers how to set up the 1Password CLI with the ngrok shell extension to store and access your ngrok credentials via 1Password. This combination gives you the speed and simplicity of ngrok protected by the power of 1Password’s vault. By integrating ngrok with 1Password, you can:
  • Store your credentials in exactly one place, limiting the risk of not updating environments after resetting tokens
  • Share credentials between environments securely, eliminating the risk of copy and pasting credentials in other tools or reusing credentials between multiple projects accidentally
  • Switch between credentials as necessary to test with different ngrok configurations, feature sets, or even accounts
Prerequisites:
  • A 1Password account
  • 1Password desktop app installed on your machine (v8 or later)
  • 1Password CLI installed on your machine (v2.14.0 or later)
  • ngrok installed on your machine
  • Basic familiarity with the command line
Tip: One of the easiest mistakes is failing to connect the App to the CLI. In the 1Password App, go to Settings > Developer and select “Connect with the 1Password CLI”

​
1. Initialize the 1Password ngrok shell plugin

To configure the ngrok shell extension, open a terminal and run this command: 
op plugin init ngrok
If you are logged into the 1Password app, you will be presented with a permission request: Initialize the 1Password ngrok shell plugin Otherwise you will be forced to authenticate and then will be presented with this request. Choose “Allow Access” and you will be presented with a command line option: Import your ngrok credentials into 1Password For initialization, select “Import into 1Password,” copy and paste your ngrok authtoken into the command line, and hit enter. Next, give it a memorable name. Finally, choose when you want to use it. The entire configuration looks like: Import your ngrok credentials into 1Password

​
2. Clean up your ngrok.yml file

Now that your credentials are safely in your 1Password vault, you can remove them from your local environment. Use your text editor to update .ngrok2/ngrok.yml and remove the authtoken value: 
vim .ngrok2/ngrok.yml
You can delete the entire authtoken line right now but to test safely, you can alternatively prefix the line with a pound sign (#). Either way, ngrok will no longer find and use that value.

​
3. Start your tunnel

Now that the environment is configured, start the tunnel. 1Password will intercept the request, determine which credential to use, and start a tunnel as requested. Import your ngrok credentials into 1Password By following this guide, you have successfully integrated the 1Password CLI with ngrok, allowing you to securely manage your ngrok credentials and even choose between multiple credentials at runtime to demonstrate and test under different configurations.
