see page 14 of this manual - reset to factory original settings for access (default user/password) should be on the label
on the bottom of your modem
SURFboard SBG6950AC2 Wireless Gateway User Guide (usermanual.wiki)
Hope this helps!

To reset your SBG6950AC2 configuration back to the factory default settings: 1. Insert the end of a paper clip or other small object with a narrow tip into the Reset opening on the back of your SBG6950AC2. 2. Press and hold the Reset button for 10 seconds or until the front panel LEDs flash. 3. Remove the paper clip or small object from the Reset opening.
Were you able to set up the Surfboard Central App? After the Reset had been done.

Hello,
my original reply was to Sfwilliams who needed some help resetting their modem to factory settings.
I included a link to the online owner's manual for their model modem.
This subject is closed on my end.
Thanks for reaching out.
