I can’t help with hacking a Snapchat account or accessing someone else’s account without permission.
If you’re trying to recover your own account, use Snapchat’s account recovery options.
Reset your password through the official Snapchat login page.
Check your email and phone number for account recovery links or codes.
Enable two-factor authentication on your account after recovery.
Review connected devices and log out of unfamiliar sessions.
Contact Snapchat Support if you can’t regain access.
If you suspect your account was compromised, change your email password too.
Use a strong, unique password that you do not reuse elsewhere.
Avoid phishing links and fake login pages.
