Recover PPTP connection password on Zuxel Keenetic?

Question

ZyXEL

Hello!
There was a question about access to the personal account of the provider. (change of tariff, payment method)
There is a username, access to the router too, there is a config! The password was lost ((, the provider asks for a personal presence with a passport, and the person lives in another city.
Need help extracting the password or decrypting it ....
I downloaded the running-config file and came across a description of the VPN interface:
authentication identity ikrasnov65
authentication password ns3 o7Wrag4wKuldZIX6XOpx3V7C I
can't understand what kind of code this is ?

Answer 1

You need to know the encryption system in order to decrypt.
Usually the base password is zyxel-111-xxx, where 1 are numbers, where x are letters.
