The login page
If you are looking for the nexus market login, it is not on this site. It is a page inside the .onion you opened. The link to it is on the market's own home page, usually in the top bar of that site. Not a pop-up, not a redirect. If clicking "login" changes the address in your browser to something that is not the .onion you started with, you have left the market. Close that tab.
What the form asks
A username and a password. If you set up two-factor authentication, a second step with a code. That is the whole of it.
What it should not ask
- An email address. The market does not need one to let you in, and a form asking for it is not the market's form.
- A deposit before you can see your account. "Pay to unlock" is a phrase from a different kind of site.
- A notice that your account is "suspended" and a "recovery" service to fix it. Check the address in your browser before you believe anything on the page.
A note on passwords
Tor Browser does not store passwords by itself. If you use a password manager, save your market password against the full .onion address, so a lookalike site cannot borrow it later under a different name.
If you lost your password, the market's recovery uses the phrase you wrote down at registration. There is no "email me a reset link" option, and a page that offers one is selling you something.
