Currently Agama mobile version gives you the feature for you to secure your transactions by adding a pin that needs to be typed each time you want to send a transaction. 


You need to save this feature in "Settings" and move the button to the right side and saving the as showed below.

This option can prevent a mistake and gives an extra layer of security to your funds. After you activate this feature you will see this screen each time you want do send a transaction. Later on when you want to do a transaction you will be seeing a screen like the one below asking for your pin before being able to make the transaction happen.

You will also see a side feature that allows you to lock your wallet automatically depending on the amount that you want. Here is a screenshot of the 3 options it gives to users.

Even though you have a pin to enter the wallet and to make transactions , you should always keep a written copy of the key in a safe place. The pin is just a new feature but your seed holds the private keys for all of the coins that you manage under your wallet if some reason your cellphone gets lost or something else out of your control happens.
