Couldn't we just use the reset code for registration ?
Rather than asking for a password, invoke the resetter,
so this would also automatically serve as a kind of
email confirmation (no email control, no known password).

And we then need to delete accounts that are not used within
a given amount of time, as per https://trac.osgeo.org/osgeo/ticket/1675

PS: osgeo trac is being spammed now, could anyone setup the proper
    configuration and BadContent page ? I'm gone for today.
