Facebook blocked - identification on another device does't work.

Hello,


I have a personal Facebook account, and I'm not able to login to that account. Facebook is asking to

Confirm my identity on another computer

Confirm your identity
To continue, please confirm your identity on a phone or computer that you've used before.

I tried with all previous used computers and phone's and it doesn't work. I can't access my account.

Please help me with this. It is very important for me.
Thanks in advance!
