192.168.100.1 Username and Password
If you are looking for the username and password for 192.168.100.1, the honest answer is that it depends on your specific modem and internet provider, because 192.168.100.1 is usually a modem address, and different manufacturers set different credentials. Often it does not require a login at all. This guide explains the common defaults, why many 192.168.100.1 pages open without a password, and where to find the exact credentials for your device.
Why There Is No Single Answer
192.168.100.1 is typically the address of a cable or fiber modem rather than a Wi-Fi router, and modems are made by many different companies, each with its own defaults. Your internet provider may also customize the login before sending you the equipment. That is why a single universal username and password does not exist for this address, and why a credential that works for one person fails for another.
So the right approach is to try the common defaults below, and if those do not work, read the exact credentials from your modem’s label.
Many 192.168.100.1 Pages Need No Login
Here is the part that surprises people. On a lot of cable modems, the page at 192.168.100.1 is a status or diagnostics page that opens without any login at all. It shows your connection details, signal levels, and line status, information meant for viewing rather than changing, so it is not always password-protected.
If you typed 192.168.100.1 and went straight to a page of connection statistics without being asked to sign in, that is normal. There may simply be no login required for the information you are viewing.
Common Default Usernames and Passwords
When a login is required, these are the combinations most often used on modems that sit at 192.168.100.1. Try them in order.
| Username | Password |
|---|---|
| admin | admin |
| admin | password |
| (blank) | (blank) |
| admin | (blank) |
These cover a large share of cable and fiber modems. Both fields are usually case-sensitive, so enter them in lowercase as shown. If your modem came from an internet provider, they may have set a unique password, which is printed on the device rather than matching any of the generic defaults above.
Where to Find Your Exact Credentials
The most reliable source is the label on the modem itself, usually a sticker on the bottom or back. Look for lines marked something like Username, Password, or Admin, which list the credentials set for your specific unit. Many modern modems use a unique password printed here rather than a shared default, so this label is the definitive answer for your device.
If the label does not show login details, check the modem’s manual or your internet provider’s documentation. Provider-supplied equipment sometimes has its credentials listed in the welcome paperwork or the provider’s app or account portal.
What to Do If None of the Credentials Work
Confirm you actually need a login. If the page shows connection diagnostics without prompting you, you may already have all the access that page offers.
Check the label carefully
The correct password is often printed on the modem, and it may be a unique string rather than a simple word. Enter it exactly, watching for similar-looking characters like the number 0 and the letter O.
Contact your provider
For provider-supplied modems, some management is reserved for the provider, and they can tell you the credentials or make changes for you. This is common with ISP equipment.
Consider whether you want your router instead
If your goal was to change your Wi-Fi name or password, that is usually done on your router, not at 192.168.100.1. Your router is typically at 192.168.1.1 or 192.168.0.1, with its own separate login.
A Last Resort: Factory Reset
If you set a custom password on the modem and have genuinely forgotten it, a factory reset restores the original credentials. Be cautious, though: resetting a modem can clear the settings that connect it to your provider’s network, which may interrupt your internet until it is reconfigured. For provider-supplied equipment, it is safer to contact the provider before resetting. If you do reset, hold the recessed reset button on the modem for about 15 seconds, then log in with the default credentials from the label. For the full process, see our 192.168.100.1 login guide.
Conclusion
There is no single username and password for 192.168.100.1, because it is usually a modem address and the credentials vary by manufacturer and provider. Start by trying admin/admin and admin/password, but know that many of these pages open without a login at all, and the definitive credentials for your device are on the modem’s label. If you were really after your Wi-Fi settings, those live on your router at an address like 192.168.1.1, not on the modem at 192.168.100.1.
Frequently asked questions
What is the default username and password for 192.168.100.1?
It varies by modem and provider, since 192.168.100.1 is usually a modem address. The most common combinations are admin/admin and admin/password, but many modems use a unique password on the label, and some pages need no login at all. Check the sticker on your modem for the exact credentials.
Why does 192.168.100.1 open without asking for a password?
On many cable modems, the 192.168.100.1 page is a diagnostics or status page meant for viewing connection information, not changing settings. That kind of page is often not password-protected, so you reach it directly without signing in.
admin/admin does not work at 192.168.100.1. What now?
Try admin/password, then a blank username and password. If none work, your modem uses a unique password printed on its label, so check the sticker. For provider-supplied equipment, contact your internet provider, who may hold the credentials.
Where is the password for my modem printed?
Usually on a label on the bottom or back of the modem, marked with something like Username, Password, or Admin. Many modern modems use a unique password here rather than a generic default, making the label the most reliable source.
I want to change my Wi-Fi password, not view diagnostics. Where do I go?
To your router, not 192.168.100.1. The modem at 192.168.100.1 typically handles the connection to your provider, while Wi-Fi settings live on your router, usually at 192.168.1.1 or 192.168.0.1, with its own login.
Is it safe to reset my modem to recover the password?
It restores the default credentials, but resetting a modem can clear the settings that link it to your provider's network, possibly interrupting your internet. For provider equipment, contact them first rather than resetting yourself.
