Root Cause

Redis requires authentication but the client did not send AUTH, or sent wrong credentials. Redis 7+ supports ACL users.

generic

Workarounds

  1. 95% success Configure the client library with the correct password 
    redis-py: Redis(host='...', password='secret'); or redis-cli -a secret

    Sources: https://redis.io/docs/latest/operate/oss_and_stack/management/

  2. 88% success Use ACL users for fine-grained access control (Redis 7+) 
    ACL SETUSER appuser on >password ~app:* +get +set  # limit commands and key patterns
  3. 85% success Store credentials in environment variables or a secrets manager 
    REDIS_URL=redis://:password@host:6379/0; or use HashiCorp Vault, AWS Secrets Manager

Dead Ends

Common approaches that don't work:

  1. Disable requirepass in redis.conf to remove authentication 90% fail

    Removes all access control; any client can read/write/flush all data. Critical security risk.

  2. Hardcode the password in application source code 80% fail

    Credentials in source code get committed to version control and exposed in logs
