Hey there @TSheena!
Would you be able to share any additional information such as which Square product you're seeing this issue on? If you are unable to access an account due to a passcode, the first port of call would be Square Support, unfortunately as this is a public forum Square support staff and community members are not able to provide any account specific support for you here.
Give them a phone call and they'll be happy to help.
If this helps, please mark it as best answer to help others in the future!
