When you install Xumm, the first thing it asks you to do is to enter a 6 digit passcode.
This 6 digit code is one of the primary ways to access the Xumm application. (The other way is via Biometrics) If, during the installation of Xumm, you did not select "Extra Security", the 6 digit passcode is also one of the ways to sign a transaction.
I have my 6 digit passcode, I just want to change it
To change your passcode, launch Xumm, press Settings then Security then Change passcode. Enter in your current passcode, then enter in your new passcode. You have 1 million possible combinations to choose from. This is one of the primary security measures for protecting your funds so do not choose, 123456, 000000, 11111 or something similar. Your passcode should be difficult to guess.
My 6 digit passcode code is not working
Your passcode will not work if you migrated Xumm (e.g. restoring from a backup from your phone, or another phone in case you obtained a new one). In case where your passcode is no longer working, you are going to need to uninstall Xumm, then reinstall Xumm and reimport your account using your account secret. This article explains:
I lost my 6 digit code and I need to create a new one
In a case where you have lost your passcode, the solution is the same as if your passcode is not working. Uninstall Xumm, then reinstall Xumm and reimport your account using your account secret. This article explains:
As mentioned earlier in this article, there are 1 million different combinations to choose from when deciding on a passcode (000,000 to 999,999). Your passcode is required to open Xumm, which of course means that, to be abused, someone would first need to obtain access to your phone, and unlock your phone.
This is one of the primary security measures for protecting your funds so do not choose, 123456, 000000, 11111 or something similar. Your passcode should be difficult to guess in the event that you phone is ever stolen.
