Do modern smart phones use 4-decimal-digit PINs as the only encryption key?

 

I only have a dumb phone, and it uses a 4-decimal-digit PIN, and a 5-digit one for some operations such as resetting the 4-digit PIN and accessing voice mail messages.

 

I'm just curious, since phone security has been in the news so much lately.

Thanks.

 

In that case, it's odd that anyone would consider that secure.

It's not the only method.

It doesn't have to be four, or digits.

What other methods are there? Could you, for example, use a twelve-character alphanumeric PIN?

I found an online iPhone manual that said in the "advanced settings" you could select that the passcode be alphanumeric, up to 12 characters.

You CAN. I was talking about the default...

Yes, I know. I was merely adding some informative data to this valuable topic. :sunny:

 

Does that default include alphanumerics or just decimal digits? In any case, I suppose that 99% of people are going to choose weak passcodes anyway. Two extra characters won't make much difference to a brute-force attack.
