ah. yes. i was counting the last = sign, sorry.
"=" signs are only added if the input isn't a multiple of 3 bytes:
$ echo -n "abc" | base64

My experience is also that 16-character base64 passwords are accepted
most of the time, as long as the generated password has a mix of
upper-case/lower-case/digits.
There are some sites which require a special symbol. However I also
recently came across a site which rejected a base64 password because it
did not allow + or / in a password. You can't have one algorithm which
always works :-(
