Factory reset on android mobile but remembered my wifi password

[Xcandyman]

Hi,

Bit confused here and wondered if anyone else has experienced this. I've just done a factory reset on my android phone and after it booted back up it automatically logged into my router even with it being password protected. Anyone else has this with Android? It's the latest version and the mobile is Samsung Galaxy Y.

Thanks

Thanks for the reply. I don't think I've ever chose Google to backup my data but my guess it that is what's happened. Not to sure that I like the big G keeping my router password like that, may have to look into account settings to stop it.

Thanks again
