I've downloaded an apk file of secure folder on my phone even though it's not meant to be one my phone and it worked kind of perfectly but I've changed the password and forgot it and after failing couple of times it requires me to sign in to my samsung account but because it's not installed by me not the company it turns to Sign Page every

• I've tried to uninstall it and didn't work
• Tried to backup my data with smartswitch still require me to sign
