i am in dead end that's why i am here for some help.

My s6 edge was locked by finger print. all was working good. But today while i was on bath my child was playing with my mobile and by mistake they tried finger printer server time lead my device to locked.

Now my device asking for backup password but as the password was alphanumeric 12 digit long i forgot that also. i searched a lot on Google and found either Google account or resetting the device is only solution.

but i can't even use Google account as my WiFi and/or mobile data was off when my phone was lock mode. Now for damn Google security system i can't even enable WiFi or mobile data?

so, my question is:
1. is there a way to make my device to ask for my finger print once again?
2. or is there a way to on my WiFi or mobile data on lock screen?

because i really want to rest my device as i have so many unsaved data :(

thanks in advance

best regards
