I use a password manager, which I checked and didn't have a password specified for the app. Having said that, it is possible that I failed to record it.
I previously did not enter a password to open the app (Android), but after upgrading the app, it now asks for one.
Enter your user ID and click "forgot Password" on the login screen and it will take you through a process to set a password.
As long time reliable expert @Lite Beer has already stated, no problem. I've done my extension on the date of expiry (Due to unforeseen circumstances) in the past. Just make sure all your docs are in order.
