How to fix NOAUTH Authentication required in Redis

Connect to Redis using redis-cli with the -a flag to provide authentication:

redis-cli -h 127.0.0.1 -p 6379 -a your-password

Replace your-password with your actual Redis password.

If you are already connected to Redis, you can authenticate mid-session using the AUTH command:

AUTH your-password

After successful authentication, you can execute any Redis command.

For most Redis client libraries, include the password in the connection URL:

Node.js (node-redis):

const redis = require('redis');
const client = redis.createClient({
  url: 'redis://:[email protected]:6379'
});
await client.connect();

Python (redis-py):

import redis
r = redis.Redis(host='127.0.0.1', port=6379, password='your-password')

Java (Jedis):

Jedis jedis = new Jedis("127.0.0.1", 6379);
jedis.auth("your-password");

Go (go-redis):

rdb := redis.NewClient(&redis.Options{
    Addr:     "127.0.0.1:6379",
    Password: "your-password",
})

Check that the Redis server has requirepass configured in /etc/redis/redis.conf:

grep requirepass /etc/redis/redis.conf

The output should show something like:

requirepass your-password

If requirepass is commented out or absent, no authentication is required. If the password on the server differs from what you are using in your client, update one to match the other.

If changing the password, use a strong, randomly generated password. You can generate one with openssl:

openssl rand -base64 32

Update the requirepass setting in redis.conf and restart Redis:

sudo systemctl restart redis-server

Then verify connection with the new password.
