Setup Redis Password:

To make your Redis service secure it is always better to setup strong password

sudo nano /etc/redis/redis.conf

Remove # from requirepass update the password:

requirepass <your-strong-password-here>

Generate Strong Password for Redis:

Instead of creating a password by yourself we can generate a very strong password using openssl use following command to generate the strong password:

openssl rand 60 | openssl base64 -A

You can again open up the redis.conf file and update the requirepass with new password you have generate.
