Suddenly, the password of the RDS was wrong as above, so access was not possible.
- Was not in AWS maintenance
- We're not working on anything
- We didn't change the password
- Monitoring figures were not unusual
Access is possible after resetting the maste* password.
I've never experienced anything like this before.
I'm worried that this will happen again in the future. I wonder why the password was deleted.
I'd appreciate it if you could tell me the cause and prevention method.
