Typing a Wi-Fi password is annoying, especially when the password is long and secure.
A Wi-Fi QR code makes the process easier: guests scan the code and their phone can
join the network.

The [Wi-Fi QR Code](/tools/wifi-qr-generator/) tool builds that QR code in the
browser.

## The simple idea

A Wi-Fi QR code stores the network details in a standard text format. It usually
contains:

- network name;
- password;
- security type;
- whether the network is hidden.

A phone camera reads the QR code and offers to join the network.

## Step 1: know the network name

The network name is also called the SSID.

Example:

```text
Office-Guest
```

Type it exactly. Wi-Fi names are case-sensitive in practice. `Office-Guest` and
`office-guest` should be treated as different names.

## Step 2: choose the security type

Most modern home and office networks use WPA or WPA2. In the tool, this is usually
the right choice for normal password-protected Wi-Fi.

Common options:

- WPA/WPA2: normal modern Wi-Fi with password;
- WEP: old and insecure, only for legacy networks;
- no password: open network.

If you are unsure, WPA/WPA2 is probably correct.

## Step 3: enter the password

Enter the Wi-Fi password exactly as configured on the router.

Check:

- uppercase letters;
- lowercase letters;
- numbers;
- symbols;
- spaces at the beginning or end.

A QR code cannot fix a wrong password. If the password is wrong, scanning will fail
or the phone will not connect.

## Step 4: mark hidden network only if needed

Most networks are not hidden. Leave the hidden option off unless the SSID is hidden
on purpose.

A hidden network is not a strong security feature. It mainly changes how clients find
the network.

## Step 5: generate and download the QR code

Open [Wi-Fi QR Code](/tools/wifi-qr-generator/), fill the fields, then generate the
QR code.

Download it as an image if you want to print it or place it in a document.

For guest access, I like to include a small label near the code:

```text
Scan to join Office-Guest Wi-Fi
```

Do not print the password next to the code unless you intentionally want people to
see it in text form too.

## Step 6: test with a phone

Before sharing or printing, test the QR code.

Use at least one phone camera and confirm:

- the phone recognizes it as Wi-Fi;
- the network name is correct;
- the phone can join successfully;
- the printed size is large enough to scan.

If the QR code is too small or printed with low contrast, scanning may be unreliable.

## Step 7: treat the QR code like the password

This is the important privacy point: a Wi-Fi QR code contains the Wi-Fi credentials.
Anyone who can scan or photograph it may be able to join the network.

So treat the QR code like the password itself.

Good places:

- guest room;
- office reception area for guest network;
- rental property welcome sheet;
- internal team document with access control.

Bad places:

- public website;
- social media photo;
- visible window facing outside;
- screenshot sent to a large group by accident.

## Step 8: prefer a guest network

If possible, use a separate guest network instead of your main private network.

A guest network can limit access to internal devices such as:

- laptops;
- printers;
- NAS devices;
- smart home devices;
- admin panels.

The QR code is convenient, but network separation is still the better security
boundary.

## Step 9: rotate the password when needed

If the QR code was shared too widely, change the Wi-Fi password and generate a new
QR code.

Printed QR codes do not expire by themselves. They stay valid until the network name
or password changes.

## My Wi-Fi QR checklist

Before sharing a Wi-Fi QR code, I check:

1. Is the SSID typed exactly?
2. Is the security type correct?
3. Is the password correct?
4. Is the hidden-network option correct?
5. Did I test the QR code on a phone?
6. Is the printed code large and clear enough?
7. Is this a guest network, not the private main network?
8. Am I comfortable with anyone scanning this code joining the network?

A Wi-Fi QR code is a convenience tool. Use it like a password that happens to be
scannable.
