Hey @Salah, 
Thanks for your post. We cannot help you access your Facebook account, however, if you previously logged into Strava using Facebook you can use the password recovery process. Click HERE and enter the email address used in your Facebook account. You should receive a link to reset your Strava password within minutes.

If that doesn't work, you will need to submit a support ticket and someone from our Support team will be able to further assist you. The Community Hub & Strava Support are two different platforms. The Hub is great for general questions and information while our Support team will handle questions that require account access.
