Re: How secure is Email based password reset?

the problem with email is that you are send messages using
plain text. if a would be cracker was sniffing your out bound
port then you might have a problem with sending passwords
through emails.

could you give your client's pgp or similar keys and
encrypt emails if it contains passwords?

One of the ways to implement the password reset is to
1. Ask the personal question
2. if correctly answered, generates a unique temporary password
3. Send the password over email to user.
What if the user says I won't be able to check the email at that
address till the end of day but could you please send it to
blah () hotmail com?

4. This would allow user to login once.

My query is regarding sending the password over email to user. How secure is
it? Given that,
1. The Server would be delivering the password email to an Internet Service
Provider.
2. The user would typically be online waiting for the password emal to
arrive.
3. The password would be invalid after the first use.
How valid are these assumptions?

Any other pointers about different way of re-setting the password would be
helpful.
