Authentication failure

[yuki8401]

The problem we are facing is how to login into the fortiwifi device.

We put username: admin and password: leave blank as the manual instructed but it is not working. And it shows " Authentication failure", how can solve this problem?

Looks like someone has set the password already.Is this a new device? If you can't find the password, you may need to reset it as described in https://community.fortinet.com/t5/FortiGate/Technical-Tip-Resetting-a-lost-admin-password/ta-p/19704...

Hello

It looks like someone has already set a PW.

I would like to reset the AP.

Ensure you're using the correct default credentials. If the issue persists, try a factory reset or contact technical support.

You might be dealing with a device where the default login was changed before. A factory reset usually restores the blank-password login, so that’s worth trying if nothing else works. Had a similar issue once while checking some tools on https://thepvzfusion.id/ , and a simple reset saved a lot of time.
