Returning to P1999 - Recovering Passwords etc?

[Mortimer]

So I've been away from P1999 for about a year or more, logging back in is giving me issues.

Presume I've forgot my password, I keep getting a 'DB Error - Invalid Password'

I'm not sure if its recoverable, from rereading the instruction its suggested I provide an SMS, but I'm not sure if thats to late after the fact now (or where I enter it).
