Securing the Auth Token
Securing the Leader’s Auth Token
Cribl strongly recommends that when you first install Cribl Stream, you change the Leader’s auth token value from the default criblmaster to a unique secure value.
This applies whether you configure your Leader via the UI, or via a Docker Compose file.
Changing the Default Auth Token Value
Create a unique, strongly secure token value. Cribl recommends creating a string that contains at least 14 characters and includes uppercase letters, lowercase letters, and numbers.
One option is to generate a token value with a shell command. For example, on Linux or Mac OS, the following command generates a 32-character value:
head /dev/urandom | LC_ALL=C tr -dc A-Za-z0-9 | head -c32 | cut -c 1-Once you have created a secure auth token value, paste it into the Auth token field in the UI, or in the appropriate place in your Docker Compose file (if applicable).
In the UI, you’ll find the Auth token setting under Global Settings > System > Distributed Settings > Leader Settings, as shown in the screenshot below.
