API token for Subfinder

Subfinder finds subdomains from passive sources. With an ActiveDNS token it also gets the names ActiveDNS has seen resolving under a domain.

Coming soon: ActiveDNS support is being submitted to Subfinder and is not in a release yet.

Once your Subfinder version includes ActiveDNS (subfinder -ls lists activedns), add the token to ~/.config/subfinder/provider-config.yaml under activedns: and check it with subfinder -d example.com -s activedns. The page you reach from the e-mail shows the exact lines; more on the Subfinder tool page.

Enter e-mail address and we will send you a link.

We do not collect email addreses and will not use it for anything else than granting you a token.

Requesting a token makes your browser solve a short proof-of-work puzzle (a few seconds) instead of a captcha.
