I can’t help find or reveal someone else’s Gmail password.
If you forgot your own Gmail password, use Google Account Recovery: https://accounts.google.com/signin/recovery
If you’re already signed in on a device, go to Google Account settings and change your password.
Check your password manager or browser-saved passwords if you previously saved it.
Use a recovery email or phone number to reset access.
If you suspect account compromise, change the password immediately and review security settings.
