# Login Bypass
## **Bypass regular login**
If you find a login page, here you can find some techniques to try to bypass it:
* Check for **comments** inside the page \(scroll down and to the right?\)
* Check if you can **directly access the restricted pages**
* Check to **not send the parameters** \(do not send any or only 1\)
* Check the **PHP comparisons error:** _user\[\]=a&pwd=b_ , _user=a&pwd\[\]=b_ , _user\[\]=a&pwd\[\]=b_
* Check credentials:
* [**Default credentials**](../../brute-force.md#default-credentials) ****of the technology/platform used
* **Common combinations** \(root, admin, password, name of the tech, default user with one of these passwords\).
* Create a dictionary using **Cewl**, **add** the **default** username and password \(if there is\) and try to brute-force it using all the words as **usernames and password**
* **Brute-force** using a bigger **dictionary \(**[**Brute force**](../../brute-force.md#http-post-form)**\)**
