Unlike most social media websites, there is no way to recover your account if you lose your password / owner key! This is why it is extremely important that you save and backup your password somewhere safe. It is strongly recommended that you store an offline copy in case of a hard drive failure or other calamity. Consider digital offline storage, such as an external disk or flash drive, as well as printed paper stored in a fireproof safe. Use a safe deposit box for best redundancy.
If you leak your private key to another user or a third-party website, that user or website will have full access to your account. This means they can steal it, as well as the funds inside of it. It is therefore not recommended to enter your private key information with any other user or third-party website. If you believe your account has been compromised, you should change your password/keys right away.
Each account has multiple keys, which each have different levels of authority: owner, active, posting, and memo. The information on the different types of keys and their purposes, as well as more information on password and key security, can be found in the section on Security.
