How to Use Invisible Ink to Add an Additional Layer of Protection to Your Passwords Backups

Nowadays the average internet user has tens of accounts. And, ideally, each account has a strong and unique password to avoid a single point of failure in case of a hack or a data breach.
But, while having strong and unique passwords for each account is very advisable, this makes it quite a challenge to remember all those passwords. Because of this, many people rely upon password backups.
Having paper backups of our passwords is a very valid method if we can protect written information from intruders or curious visitors.
But, even if our paper backup is stored in a safe place, it is a smart move to add a layer of protection by using invisible ink.

3 Factors You Need to Know About Using Invisible Ink

To use invisible ink as an additional layer of security for password backups, two main points need to be considered:

 
Fist Factor - The Invisible Ink Marker

Not all invisible ink markers are reliable or suitable.
The ink of some markers quickly fades over time and it may be just a matter of weeks before the text becomes illegible.
And some other markers deliver far too much ink or have too wide writing tips which also makes them unsuitable.
Choosing the correct marker is probably the most important aspect when using invisible ink.

 
Second Factor - The Ultraviolet Light Source

While choosing a UV Flashlight is not as important as choosing the best invisible ink marker, it does really help to have a reliable source of UV light.
There are several options available on the market, but you may consider getting an easily concealable and low-consumption UV flashlight.
 

Third Factor - The Most Suitable Paper

Along with the UV marker, the paper is a very important factor when using Invisible Ink.
A high-quality paper will ensure that the ink will be absorbed and will remain intact for a very long period.
On the other side, low-quality paper or special types of paper, like stone paper, will lead to incorrect ink absorption, ink smudges, or ink degradation.
