If the login name is unique and you don't allow multiple simultaneous
logins then the chanve of a mixup is exactly zero.
If you are talking about session IDs, I believe they are 128 bits which
translates to a chance of duplication of 1 in
340,282,366,920,938,463,463,374,607,431,768,211,456 [the result from
bcpow(2, 128, 0)]. Should be good enough :-).
