Do I need to verify every time I run it?

Do I need to verify every time I run it?

Not every time you run the executable, but each time a new version is released. You must verify the files before installing them.

When I look at the digital signature list for the installation file I used I am seeing "Bitcoin Core Code Signing Association", is that normal? I have v0.21.0

As far as I know, the 'Bitcoin Core Code Signing Association' is a new certificate used by the Bitcoin Core team. Before v0.16, the installer signed by The Bitcoin Foundation.

Final Windows and Mac installers are digitally signed by *'Bitcoin Core Code Signing Association'*. On Windows, you can check this by right clicking the installer, choosing properties, and then going to the Digital Signatures tab. Check that it is signed by *'Bitcoin Core Code Signing Association'*. (Note that prior to v0.16, installers were signed by The Bitcoin Foundation but the signing certificate expired, so Bitcoin Core developers [acquired new certificates](http://gnusha.org/bitcoin-core-dev/2017-11-09.log).)

Make sure you download Bitcoin Core from the official site, i.e .:
https://bitcoincore.org/en/download/
And verify the PGP signature. Look at the 'Verify release signatures' link.

You have the option of verifying or not verifying the signature

There is no need to verify the GPG signature every time you run Bitcoin Core, just once when you want to install or update to the latest version. Although you can also ignore this process, checking the authenticity of the software through the GPG Signature verification from the original developer is highly recommended to minimize if you accidentally download Bitcoin Core from a fake link.

how to verify it, anyone can help me.

You can verify the Bitcoin Core application using a terminal (command line prompt) or a third-party application such as Kleopatra or GPG keychain.
Here is an example of the verification results on macOS using the terminal:

You can see some instructions for verifying Bitcoin Core here (subtitle 'Verify your download'):
https://bitcoincore.org/en/download/.
Or you can also use software like Kleopatra (Windows OS) to verify Bitcoin Core. Or, if you are a macOS user, you can look at my previous post:

Only a stupid person would fail to verify before running the core software on their computer. At this day and age where hackers need just one silly mistake to clean ones stack of coins, it is paramount to be security concious before using downloadable softwares...before use, verifying using a command line prompt or other third party applications available is wise.

I downloaded Bitcoin Core yesterday.
Name of signer:
Bitcoin Core Code Signing  LLC


Not Foundation like before, not Association like prwvious year.
But LLC!
Is it OK?
Is it legit?
Is it real signature?

[vv181]

Updates the Windows code signing certificate to a new one issued by Digicert. This certificate has been issued to Bitcoin Core Code Signing LLC registered in Delaware, US. Note that this is different from the previous Bitcoin Core Code Signing Association registered in Zurich, Switzerland as it was unable to meet the validation requirements in time.

Yes, it looks like there is a change of signing certificate and the guide on the first post hasn't been updated. If you want to make sure, just try the other verification options.

[Gorilla22]

The most important is if  they who are behind this LLC are the same people like before, not scammers or thieves. If they are the same good guys, then may be the only thing which is necessary is updating the first post in this thread? Or what do you think?
IMHO (as I am an unexperienced newbie).

[vv181]

The same developers still manage it as before, you can see on the referred link above, the one who tells it is @achow101, which is one of the bitcoin contributors.

Just a side note, it may be registered as LLC due to the requirement for acquiring the certificate. I think it's better not to rely on the Windows code signing certificate, I don't know how verifiable it is to be able to verify or check the authenticity of the software itself. You better use the second option, which was using the PGPs method. The guide on how to do it is also available on the Bitcoin Core Website(https://bitcoincore.org/en/download/).
