Keychain Access Help

Keychain Access->Help->Keychain Access Help should do the trick. For other security issues, see Mac OS X 10.6 Security Guide

Ah! The proverbial missing information bit again. Provide all the details on what you've tried, what didn't work, and responders, including me, won't repeat ourselves or muddle your head with discourtesies. I use KA for all my internet passwords, but don't use debit cards or an iPhone, so can't respond to those. Again, if you'd have provided those details, I most likely would have passed on responding. Have a good day.

This information is from the Keychain Access help:

Storing confidential information in your keychain
You can use your keychain to securely store sensitive information unrelated to your computer, such as personal identification numbers (PINs) for a bank account, credit card numbers, confidential notes, cryptographic keys, and any other information that you want to keep private.

Storing information in your keychain:

Open Keychain Access, located in the Utilites folder in the Applications folder.

Open Keychain Access
If keychains are hidden, choose View > Show Keychains.

Select the keychain you want to use.

If the keychain is locked, click the lock icon, and then enter your keychain password to unlock it.

Choose File > New Secure Note Item.

Type a name for the note that will help you remember what it is.

Type or paste the information you want to preserve in the Note field.

Click Add.

Enter a password if required.

To view the contents of the note, select Secure Notes in the Category list and double-click the note. Select Show Note. You’ll be asked for your keychain password if you haven’t selected “Always allow access to this item” in the Access Control pane.

NOTE:It’s a good idea to leave “Always allow access to this item” unselected for most items in your keychain. This provides greater security for your information.

There may be other applications that utilize keychain for this purpose but I have never used them.

can I please ask you not to refer me to the Help Menu again, unless you are making reference to someplace specific? This is slightly discourteous

If you ask a generic question that sounds like it could be answered by reading the documentation, then I fail to understand how it is discourteous to point you to the documentation. Further, expecting an expert to explain something to you because you can't be bothered to read that documentation is very discourteous. It gets very old to those who have been here a while.

I have already searched the Help prior to posting.

Did you search it, or did you read it? If you read it, you should have some more specific questions. The keychain is pretty straightforward, so without more information about what you are trying to learn about, the documentation is the best thing we have to refer you to.
