 * I am using defender plugin with SMTP plugin. After a few months, my SMTP stops
   working. I’m wondering if Defender may be changing salts?
 * How to fix this in Defender plugin?

 * Hi [@assad1999](https://wordpress.org/support/users/assad1999/)
 * I hope you are doing well.
 * Salt rotation is part of one of security features: [https://wpmudev.com/docs/wpmu-dev-plugins/defender/#recommendation-update-old-security-keys](https://wpmudev.com/docs/wpmu-dev-plugins/defender/#recommendation-update-old-security-keys)
 * Ideally the plugin developers would implement custom keys that are not relying
   in the WordPress default ones.
 * If you wish to prevent Defender from resetting them, you can disable that security
   feature, but could you please let us know which SMTP plugin you are using? I 
   know some are already having what I described before.

 * I am using Fluent SMTP.
   Just a quick question:Do we need only to uncheck this
   box? What happen after 60 days? Will they again automatically regenate the salts?
   I have attached the screenshot below.

 * Hi [@assad1999](https://wordpress.org/support/users/assad1999/)
 * Thank you, I am afraid I couldn’t find anything on Fluent SMTP docs about custom
   security keys.
 * The shared image is returning 404, but by unchecking “Automatically regenerate
   security keys” it will avoid the issue, as the 60 days it is the reminder so 
   if you don’t want Defender reminding you after 60 days you can set to 1y.

 * Hello there,
   So after 60 days, It will only remind me but not regenerate the 
   keys, am I right?I have attached the screenshot.[https://drive.google.com/file/d/1dntBOTvlDyj9A6kruRn2dDfcJzaZzh3c/view?usp=sharing](https://drive.google.com/file/d/1dntBOTvlDyj9A6kruRn2dDfcJzaZzh3c/view?usp=sharing)

 * Hi [@assad1999](https://wordpress.org/support/users/assad1999/),
 * Yes, that’s right. Defender will only remind you to regenerate the keys as long
   as you have the option to automatically regenerate security keys disabled, as
   in the shared screenshot.
 * Please find more about the same in our documentation here: [https://wpmudev.com/docs/wpmu-dev-plugins/defender/#recommendation-update-old-security-keys](https://wpmudev.com/docs/wpmu-dev-plugins/defender/#recommendation-update-old-security-keys)
