Modules for Backdrop CMS

Deletes user sessions which have been idle longer than a configured time.

On busy sites, the sessions table can grow to be very large, and that can cause slow accesses to it, as well as slow writes due to locking, leading to performance bottlenecks.

Limit the number of simultaneous sessions users may have. Limits can be applied by role and per account.

Force users to log out of any extra sessions after they exceed the administrator-defined maximum.

Converts a HTML page to PDF using mPDF PHP Library.
It allows you to generate the following pdf documents of any node:

www.example.com/node/nid/pdf

Control the contents of your robots.txt file through Backdrop configuration.

Creates a virtual sitemap.txt file for indexing by search engines.

This module adds the select2 widget to all select elements in a webform.

Enforce restrictions on user passwords by defining a password policy that encourages the use of pass phrases.

This module is no longer maintained. Stripe development is now centering around
the Stripe module, including the
bundled webform_stripe functionality.

Prevent user enumeration by blocking the display of all login error messages. A user attempting to login will not be aware if the account exists, an invalid user name or password has been submitted, or if the account is blocked.

You can use this module to make an element (such as the navigation menu or
the header region) become sticky at the top of the page when a long page
is scrolled.

This module provides an additional formatter to render values in core fields as
HTML or comma-separated lists. This works with taxonomy terms, entity reference
fields, link fields, and text fields.
