How to make strong password
Create strong passwords
A strong password is an important protection to help you have safer online transactions. Here are steps you can take to create a strong password. Some or all might help protect your online transactions:
- Length. Make your passwords long with eight or more characters.
- Complexity. Include letters, punctuation, symbols, and numbers. Use the entire keyboard, not just the letters and characters you use or see most often. The greater the variety of characters in your password, the better. However, password hacking software automatically checks for common letter-to-symbol conversions, such as changing "and" to "&" or "to" to "2."
- Variation. To keep strong passwords effective, change them often. Set an automatic reminder for yourself to change your passwords on your email, banking, and credit card websites about every three months.
- Variety. Don't use the same password for everything. Cybercriminals steal passwords on websites that have very little security, and then they use that same password and user name in more secure environments, such as banking websites.

inaffective use of computer
it’s true that people have been putting computers in classrooms for many years. It’s also true that the
of these computers has often been less than wished. However, neither of those facts tell us that we should stop. Rather, they tell us to review how and why computers are being used in those classrooms.
In my own visits to schools across the country, I have seen those computers being both underutilized and over-utilized. In some schools, the computers sit idle while traditional instruction continues. Occasionally, students are allowed to use the computers, and they get to use the standard business tools available such as spreadsheets and word processors. Sure, it’s nice that the students are learning to use those tools, but are they helping students learn their subject? I think not.
In other schools, I’ve seen computer rooms fully booked so that some teachers are unable to use them at all for their students. Upon inquiry, I discovered that math and English classes have priority because of high-stakes testing. The computers have various programs on them that drill the students on concepts required on those tests. In my opinion, these schools are wasting a valuable resource.
Computers slowly and quite certainly have revolutionized many businesses. Lawyers, among the last to succumb, now cannot live without their word processors with the ability to rewrite accurately, insert boilerplate, and check spelling and grammar. Software has been created to support the advances in productivity that we’ve seen in many industries. So, what’s the matter with education?
The larger class sizes we see in schools are not the result of improved worker productivity; they’re caused by budget shortfalls. Clearly, computers have not improved teacher productivity. Students aren’t learning better. Just look at any number of international measures of student success in mathematics and science. We (the United States) are losing
