user130990: Is there a way of using bitcoin core gui in order to check if you know/correct about your wallet.dat passphrase by typing it only once?
I know you can change the passphrase, but I want to keep it and not by typing it 3 times (The other two as the 'new' passphrase).
I'm aware it might be considered a bit of an odd question, but when security is so paramount, this could matter IMO.

user51948: Yes, open the command console inside the GUI and type
walletpassphrase "your password" 1
This will only succeed if the password is correct.
If you have multiple wallets, make sure you have selected the correct wallet at the top of the console.   The console only works on one wallet at a time.
