Is a password policy a good or bad thing to have?
Information systems support teams in large and small venture capital firms often have a stringent password policy requiring all employees to create a new secure password every 30, 60 or 90 days. They frequently give strict guidelines that must be followed, such as:
- Must have both capital and lower-case letters
- Must contain both letter and numbers
- Must not be an actual word in the dictionary
To answer the very first question, yes a password policy is a good thing to have. A password is the first line of defense against the unauthorized use of your computer, data and network.
As an employee, a password policy can be a complete pain and feel like a waste of time. Password policies also raise questions of trust and can sometimes be ambiguous. Can I let other employees use my computer to get information if I am not there to help them? What if my password is already highly secure? Do I need to change the password in every program that I have a password for? Should I only change the network password? How am I going to remember a new password every 60 days?
The whole point of having a password is to make your information more secure. If you have a highly secure password that you have not written down, nor shared with anyone, you should not have to change it often. Here are suggestions to keep your password secure:
- Never share your password with anyone
- Never save a password when prompted by your browser or any other programs
- Never send your password through email
- Never write your password down
- Use different passwords for different programs

So, a password policy is a good thing, especially if you are one of the top venture capital firms. I do however think that if you create a secure password, you should not have to change it every 30, 60 or 90 days. I think creating a secure password that passes as ‘very strong’ in a password strength checker and changing it every 6 months should be sufficient if you follow the above security protocol.
