Are Cloudflare 1.1.1.1 Warp VPN keys still valid for lifetime access, and what happened to the original keys?

Originally, Cloudflare offered lifetime Warp+ keys through a promotion. However, this promotion ended, and those keys are no longer officially supported for new activations. While existing keys *may* still function for some users, Cloudflare has discontinued the lifetime subscription model. New users must now subscribe to Warp+ through regular subscription plans.
