At some point you or someone who had access to your phone created a password. If you have forgotten this then you're screwed. As far as I know, a factory reset is the way forward. Anyway, wait for others to post as I could be wrong!

Thankyou but I rang Samsung support and they have sorted it for me and didn't have to reset all my information still there and they was very helpful guiding me through it x

I have the same problem with my S20. Can you help me with contact information (phone or mail) of Samsung support?
