Is your Snapchat account locked? We're here to help you regain access! Snapchat may lock accounts if they detect unusual activity, like adding too many friends quickly, using unauthorized third-party apps, or violating their guidelines. For a temporary lock, you should be able to log back in after 24 hours. If you're still unable to access your account after a day, follow our guide on how to use the unlock form and contact customer service to restore your Snapchat account.
