## TL;DR

If you use a user other than default, send AUTH username password, because AUTH with a bare password only authenticates the default user. Pass the database password on every connection (redis-cli -a, or the password field in the client config).

## Fix

1. If you use a user other than default, send AUTH username password, because AUTH with a bare password only authenticates the default user.
   Expected: You get the expected result; the problem is gone.

## When to use

- You are setting up or using this Redis Cloud feature.
- The symptom matches: NOAUTH Authentication required - password not passed.

## When NOT to use

- Unrelated Redis Cloud issues (different feature, different failure).
- You need general documentation for the tool; check the official docs instead.

## Compatibility

## Variant phrasings

### NOAUTH Authentication required - password not passed

## Why it happens

Commands against a Redis Cloud database return NOAUTH Authentication required even though the endpoint is reachable. Redis Cloud databases always require authentication with the database password.

## Edge cases

- If your error message differs even slightly, this is probably a different issue; search the exact text.
- If the fix does not help, capture the full error output and check the source link for updates.
