Changing the Password

To generate the password hash you can use any deepstream installation with following config in /etc/deepstream/config.yml

auth:
  type: file
  options:
    path: ./users.yml
    hash: 'sha256'
    iterations: 65536
    keyLength: 32

use this command to generate the hash

deepstream hash youPlainTextPassword@123

Default password is p@123
