Instagram is currently testing a feature that allows creators to lock reels, requiring viewers to enter a secret code and a hint to access them. This innovative approach aims to boost engagement and enable creators to share exclusive content with loyal fans. For instance, hints like 'my birthday' or 'my dog’s name' could be used to unlock content. The feature was first noticed on Instagram's Design account and may also serve as a tool for promotional campaigns. However, it remains unclear when or if this feature will be widely available.
