From what I've read, long passwords are more secure than short cryptic
ones. So if the site will allow it, you're better off using a password
of "mimsy were the buroughgroves" than "xkcdcom1080". The reason is that
if someone gets their hands on an encrypted password file, each
additional character increases the number of tries they would have to
make to brute force the password by a multiple of at least 26. For
example, if a site only allowed capital letters in their password and a
password length of 1 then there would be just 26 possible passwords and
they could brute force attempt each one. For two letters there would be
26x26 or 676 combinations, 17576 for three and so on. So a really long
password can make the crack take so long as to be more than a lifetime
with today's computers.

I use a program here called pwgen to generate 20+ character strings that have
numbers, letters and symbols. These can be very strong. Also, in order for
someone to check all possible variations on a 20 character password would take
more than the available lifespan of the planet thus far.

The problem with changing your password so often, even if you use a mnemonic,
as I do, to remember several different passwords, is it there are so many of
them. Also, there are several variations within the Numonics paradigm which can
lead you to strike out on login sites that don't allow you more than two or
three attempts. In this case, I was contention that the Gmail password site
indicated that it was a strong level of security.
Be well.

so far, I haven't seen any problems. I use both mail.app here on the macbook as
well as iOS mail on the iPhone. I manage 2 gmail accounts on there and a yahoo
account as well.
For good security, it is recommended to change the password about once per
month (for the truly paranoid, once per week is the norm). doing this often
insures that your information is secure (at least for the time being). Most
people don't like going to this extreme because it requires they memorize a new
password. In the 9 years I have been using gmail, I have been hacked precisely
once. Never again after that. Again, this is all dependent on what level of
security you are comfortable with.

This message serves partially as a test of my iPhone and Gmail, having gone
through the rigmarole of changing passwords. It also is a chance for me to ask
whether anyone else's observing problems with Gmail?
Be well.
