How to change wifi password when there are two of them

Nobody can give you the exact menu. How to change wifi password depends on who made the box in the hall, and the Federal Trade Commission — which publishes consumer guidance on exactly this and has nothing to sell — says so outright rather than pretending otherwise. What it does give you is the thing the screenshots leave out: there are two passwords in there, and only one of them is the one you came for.

Read those two side by side and the priority inverts. The Wi-Fi password keeps strangers off the network. The admin password guards the room where the Wi-Fi password is decided — so changing the first while leaving the second at whatever the factory set is a lock fitted to a door with the key still taped to it. The FTC puts the consequence in one clause: it “would undo any other security steps you may be taking.”

And there is a specific version of this that catches households rather than hackers. If you are changing the network password because you want somebody off the network — a former flatmate, a neighbour who was given it years ago, an old contractor — then the admin password is the one that decides whether the change holds. Anyone who can reach the administrative side can simply read the new password, or set another one.

The FTC also names the two searches to run, which is more useful than it sounds: not one search but two, because the manufacturer documents the admin password and the network password in different places. And it gives the fallback for when neither search lands — “contact the manufacturer directly” — which for an internet provider’s router means the provider, since the box is theirs.

That list is the reason to do this on a quiet evening rather than ten minutes before a meeting. Nothing about the change is difficult; the cost is entirely in the reconnecting, and it lands on the devices you have stopped thinking of as devices.

While the settings are open there is one more thing the FTC treats as basic rather than advanced: the encryption. Its instruction is to set the router to WPA3 Personal or WPA2 Personal — “WPA3 is the newer — and best — encryption available, but both will work.” If your router offers only WPA or WEP, the agency calls those “outdated and not secure”, says to try a software update first, and if that does not produce the newer options, to “consider getting a new router”. That is a federal consumer agency saying in writing that the hardware itself can be the thing to replace.

One alternative is worth knowing before you change anything, because it may remove the reason you are here at all. The FTC: “Many routers let you set up a guest network with a different name and password”, and gives two reasons — “having a separate login means fewer people have your primary Wi-Fi network password”, and if a guest “unknowingly has malware on their phone or tablet, it won’t get onto your primary network and your devices.” If the reason you are here is that you keep handing the password to visitors, a guest network means never handing it out again.

And the step that takes one second and is easy to forget: log out as administrator when you are done. The FTC spells out why, and it is the same argument as the whole page — while you are logged in as administrator, you “are able to change passwords and otherwise manage settings that control the security of your network.” Leaving that session open is leaving the door you just locked propped with a shoe.

The floors below take it four ways: the two passwords, finding the route for your particular box, the reconnecting afterwards, and the settings worth changing while you are already in there.

What this tower will not do

It will not show you one router’s screenshots and call it the answer. The FTC itself says the route depends on the manufacturer, and the honest thing is to say what is the same everywhere.

It will not treat the Wi-Fi password as the only password. The admin one decides whether the change you just made survives, and it is the one people leave as it came.

And it will not send you to a third-party tool to do any of this. Every step here happens in the router’s own settings, for nothing, and anything offering to do it for you wants access to the thing you are trying to secure. What holds instead is simple: the two passwords, the encryption settings, the features to turn off and the guest-network reasoning are quoted from the Federal Trade Commission’s consumer guidance, listed below.
