See [AUTH feature overview](/memorystore/docs/redis/auth-overview) for more details. \n\n### Console\n\n1. Go to the **Memorystore for Redis** page in the Google Cloud console.\n\n [Memorystore for Redis](https://console.cloud.google.com/memorystore/redis/instances?)\n2. View your instance's *Instance details* page by clicking on your *Instance\n ID*.\n\n3. Click the **Edit** button.\n\n4. Find the AUTH section.\n\n - If you want to enable AUTH, select checkbox labeled **Enable\n AUTH**.\n\n - If you want to disable AUTH, deselect the checkbox labeled\n **Enable AUTH**.\n\n5. Click the **Save** button.\n\n### gcloud\n\n1. Enable AUTH for your instance by running the following command,\n replacing \u003cvar translate=\"no\"\u003evariables\u003c/var\u003e with appropriate values:\n\n ```\n gcloud redis instances update instance-id --enable-auth --region=region\n ```\n2. Disable AUTH for your instance by running the following command,\n replacing \u003cvar translate=\"no\"\u003evariables\u003c/var\u003e with appropriate values:\n\n ```\n gcloud redis instances update instance-id --no-enable-auth --region=region\n ```\n\nGetting the AUTH string\n-----------------------\n\n### Console\n\n1. Go to the **Memorystore for Redis** page in the Google Cloud console.\n\n [Memorystore for Redis](https://console.cloud.google.com/memorystore/redis/instances?)\n2. View your instance's *Instance details* page by clicking on your *Instance\n ID*.\n\n3. Find the **AUTH string** value in the **Security** section.\n\n### gcloud\n\n1. Get the AUTH string by copying it from the response body returned by the\n following command:\n\n ```\n gcloud redis instances get-auth-string instance-id --region=region\n ```\n\nChanging the AUTH string\n------------------------\n\nFollow the steps below to change the AUTH string to a new value:\n\n1. Disable AUTH:\n\n ```\n gcloud redis instances update instance-id --no-enable-auth --region=region\n ```\n2. Enable AUTH:\n\n ```\n gcloud redis instances update instance-id --enable-auth --region=region\n ```\n | **Note:** This step interrupts your client's authenticated connection because a new AUTH string is generated, invalidating the previous AUTH string.\n3. Get the new AUTH string:\n\n ```\n gcloud redis instances get-auth-string instance-id --region=region\n ```\n4. In your application, replace the old AUTH string with the new AUTH string\n and reconnect your client.\n\nConnecting to a Redis instance with AUTH\n----------------------------------------\n\nTo use AUTH and `redis-cli` to connect to your instance, see [Connecting to a Redis instance that uses AUTH](/memorystore/docs/redis/connecting-redis-instance#connecting_to_a_redis_instance_that_uses_auth).\n\nWhat's next\n-----------\n\n- View the [AUTH feature overview](/memorystore/docs/redis/auth-overview)."]]
