Perhaps something in the == Frequently Asked Questions == section like:

= What PHP and WordPress versions does the Two-Factor plugin support? =

This plugin supports the last two major versions of WordPress and <a href="https://make.wordpress.org/core/handbook/references/php-compatibility-and-wordpress-versions/">the minimum PHP version</a> supported by those WordPress versions.

As of today, that would allow us to bump the WordPress minimum to 6.7:

two-factor/two-factor.php

Line 15 in fe16f23

* Requires at least: 6.3

two-factor/.github/workflows/test.yml

Line 82 in fe16f23

- '6.3'

and bump the PHP minimum to 7.2:

two-factor/two-factor.php

Line 16 in fe16f23

* Requires PHP: 7.2

two-factor/composer.json

Line 15 in fe16f23

"php": "7.2.24"

two-factor/composer.json

Line 24 in fe16f23

"php": ">=7.2.24|^8"

two-factor/.github/workflows/test.yml

Line 70 in fe16f23

php:
