Tired of regularly logging in and clicking the “Remember me” checkbox? No more. With this plugin, once 
you have logged in and until you voluntarily log out, your blog will remember you.
The ‘Remember Me’ checkbox on the login form will be always checked, and instead of logging you in for 14 days, the expiration is set to one year.

Always Remember Me

Always checked 'Remember Me' checkbox and longer auth cookie expiration. Your blog will remember you.

Contact forms will remember user input. When the user types some input into a form, it’ll be saved automatically. When the user opens the same page again, the previous input will be pre-filled in the form. Returning clients and registrees won’t have to type again. The data is stored locally in the user’s browser and it never leaves their device.
What data is remembered and recalled:
<ul>
<li>Text inputs – all kinds, incl. telephone numbers, e-mail addresses</li>
<li>Checkbox states</li>
<li>Radio button states</li>
<li>Dropdown selects’ states</li>
</ul>
Configuration options:
<ul>
<li>Automatic data privacy infobox.</li>
<li>Include/exclude individual fields by their tag name,</li>
<li>Include/exclude pages by URL,</li>
<li>Temporary disable,</li>
<li>Clear settings from database.</li>
</ul>
So far tested with:
<ul>
<li>Contact Form 7</li>
<li>WPForms*</li>
</ul>
*In WPForms, only the standard style dropdown is supported.
More coming soon. Other plugins are likely to work, too.
This plugin was just released, and I’d like to enhance it. Let me know about any ideas or bugs. If you have a problem or a request, open a new topic here: https://wordpress.org/support/plugin/formmemory/
Love.
