for mac users
#install tunnelblickctl if not already present and add following in your bashrc file
alias con='tunnelblickctl connect YOUR_USER'

#download oathtool and pbcopy
#now find the secret key
#tr is required because oathtool gives otp with newline which is also copied with pbcopy

oathtool --base32 --totp "SECRET" | tr -d '\n' | pbcopy && tunnelblickctl connect YOUR_VPN_USERNAME
