If you use MySQL and especially AWS Relational Database Service (RDS) you have certainly a bomb in your App without any consciousness of this!
Since MySQL 5.7.4 a nice password expiring feature was introduced with 360 days default value. But this feature was enabled by default since 5.7.10. If you use AWS RDS you have set up your DB with the fancy setup pages with no warning or information about the ephemeral duration of your password. So if your database on AWS RDS is setup from 359 days go to your AWS console page and update your password quickly.
Mark : your root login is also set during the setup of your database…
