After careful consideration, we have decided to switch privacy protection service providers from WhoisGuard to Withheld for Privacy.
Namecheap says that customers will not be affected in any way and this is a change of provider they use to protect our information from the public eye. Namecheap will offer to continue to offer Whois protection , but through Withheld for Privacy.
From March 17th, 2021, any domains covered by WhoisGuard will be protected by Withheld for Privacy.
If I read it correctly, in short
We do not need to do anything
There will be a change of name in the Namecheap website and Dashboard
Currently eligible domains will continue to get free, life time Whois protection through Namecheap
