Amazon ElastiCache announces support for modifying Redis authentication tokens
Amazon ElastiCache for Redis now allows you to modify authentication tokens by setting and rotating new tokens. Redis authentication tokens enable Redis to require a token (password) before allowing clients to execute commands. You can now modify active tokens while in use, or add brand-new tokens to existing encryption-in-transit enabled clusters that were previously setup without authentication tokens. ElastiCache for Redis provides a two-step process that allows you to set and rotate the token without interrupting client requests.
