A separate system or your normal one
Frequently presented as the entry requirement. It is a genuine improvement in the wrong position in the queue.
Your normal machine, set up properly
- What you gain
- You will actually do it, which is the property that matters most. The habits that prevent real losses all work here.
- What you give up
- Traces remain on a machine that does other things, and you are trusting whatever else is installed.
- Suits
- Most readers, on their own hardware, using it occasionally.
A dedicated system
- What you gain
- Nothing persists between sessions, everything routes through the network you intended, and traces do not accumulate.
- What you give up
- A weekend of setup and ongoing friction, which is exactly the kind of cost that makes people do it once and then stop.
- Suits
- Anyone on a shared computer, anyone with higher exposure, anyone doing this frequently.
A dedicated system instead of the habits
- What you gain
- The feeling of having done the serious thing.
- What you give up
- The habits are what prevent the losses. Booting something different and then accepting an address from a stranger has protected the wrong end.
- Suits
- Nobody, and it is a common pattern.
What each one actually prevents
| Failure | Prevented by a separate system? | Prevented by habits? |
|---|---|---|
| Landing on a copied page | No | Yes, completely |
| A reused password being tried | No | Yes, completely |
| An address substituted on your machine | Largely yes | Partly, by checking the ends |
| Traces left on the computer | Yes | No |
| Somebody else using that computer | Yes | No |
The harm in presenting it as mandatory
Two bad outcomes follow. Some people are put off by a requirement that sounds like a weekend project and go and do the same thing with no precautions at all. Others install it, feel finished, and skip the cheaper steps that would actually have protected them.
The second is more common and more expensive, because a strong tool used as a substitute for a basic habit supplies confidence the habit would not have supplied.
What tips it
Who else touches the machine. That is the question a separate system answers well and habits answer not at all. On a computer nobody else uses, spend the weekend on the habits first and consider the system afterwards. On a shared or managed machine the honest answer is that a separate system is the minimum, and not doing this at all is the better one.
