Flashed their credentials, or made short work of the lower lock, or out the window, onto the roof

The steps one must take to remain hidden are endless. Then again, the amount of different strategies to remain hidden is also an endless list. Obviously it’s easier not to hide, but sometimes that’s just not an option. When the situation presents itself and you have no choice but to remain unseen if you want to be able to move forward, you have to be able to do it. On many stealth missions that you may or may not go on, you will have to force entry. Get yourself into a place that you are not allowed to be in. The ways to do that are also endless, but you want to always have options. You can’t just be a master lock pick. The art of finding your way into locked doors doesn’t always mean playing with pins until it opens. It is important to have a new identity too. A fake one. With your own set of credentials that you can flash out for the dimwitted security. You should also know your way out. Sometimes you can’t just go back the way you came. Because if things go south, you should be able to get out the window, onto the roof, on your way back to freedom.
