Members Only v1.3.0 was released this week, with support for Access Passes. This allows you to manually grant membership access to users. This is great for use cases like invoice-based billing, offline payments, complimentary access, migrating members from other systems, and more.

Access Passes have a Start Date and an End Date, letting you define the period of time the pass begins and ends. If the user logs in before or after the Access Pass dates, they will be treated as non-members. While the Access Pass is valid, users will be treated as members and have access to member-only content. Once the pass expires, the user returns to non-member status and will be unable to access member-only content.
