Answer

Is my mail password safe in the database?

Updated Email Delivery 1.7.0Tested with WordPress 7.1

Safer than usual, and the honest answer has a limit in it.

It is scrambled with a key built from the salts in your wp-config.php, which is a file and not a database row. So a copy of the database on its own — the thing that gets handed to a developer, restored onto a staging site, or left in a backup — no longer contains a usable password.

It does not protect you from somebody who has both your files and your database, or from anybody who is already an administrator on the running site. Nothing stored on a server that has to read it back could.

To keep the password out of the database altogether, set it in wp-config.php with TRML_PASSWORD (see the next question).

Still stuck? Ask the developers who wrote it. We aim to reply within one business day.
