5. **View Account Data**: In the Settings menu, tap on "Security" and then select "Access Data."
6. **View Account Data**: Under "Account Data," tap on "Posts You've Liked."
7. **View Liked Posts**: You'll see a list of posts you've liked on Instagram. You can scroll through this list to see all the posts you've liked.
Please note that this method only allows you to see a limited number of your liked posts, and it may not show all the posts you've liked if you've liked a large number of posts. Additionally, you can only access this feature through the Instagram app, not the website.
If you need to access a comprehensive list of all your liked posts, you may consider using third-party apps or services that offer this functionality. However, be cautious when using third-party apps and ensure they are reputable and secure.
