If you suspect that your Facebook account has been compromised, it is recommended to change your password immediately. Then, if you are using Facebook to sign in to apps such as Spotify or Instagram change your logins as well. This will stop the hacker from gaining access to these third-party apps through your hacked Facebook account.
A hacked Facebook account could provide hackers access to a wealth of personal information. Hackers can make use of the information for malicious motives, like sending spam to people or sending fake credit card offers. They could also use the hacked account to send threatening messages to family members, or put up a post on your Facebook timeline with your name (as in the case that you did it yourself).
One of the most frequent methods hackers gain access to an account is when they exploit an error in Facebook's application code.

These tokens, which are digital keys, grant the hackers complete control over the user's Facebook Account, as well as any other website they log into with their https://www.app-ink.net/what-you-should-know-about-youtube-music Facebook credentials.
A hacker can also gain access to a user's account through brute force attacks. This technique involves guessing a password, typically the most commonly used ones like 123456789 or 1234567890. Additionally, hackers can gain access to an account by scanning for compromised credentials. There are numerous free tools that can be used to search for stolen data, including a popular site called HaveIBeenPwned.
