Put an end to the nonsense with a piece of paper.
There are reasons to keep it better offline and analog. Your encryption passphrase is of comparable strength/entropy to entropy of your wallet's random seed which is represented and backed up by mnemonic recovery words?
Humans are usually not good at generating sufficiently decent entropy, regarding your encryption passphrase.
With your proposal you rely on safe backups of your encryption passphrase AND safe backups of your PGP secret key AND one or multiple safe hosts for your upload. Sounds like a lot of reliance to me.
Cloud storage data centers can suffer data loss (happens rarely, but there have been severe cases). And don't forget, the cloud is just someone else's computer(s).
But if your security phase consists of 12 words then it can be easily memorized. But memorizing security phase is very difficult if it is 24 words.
Lol, why are 24 recovery words "very difficult" when 12 recovery words can be "easily memorized"? Are you serious?
But in my case I saved the security phases in a document so that I can easily retrieve my security phases.
Likely the worst storage option. Unencrypted document? Online computer? Any backups? Good luck with your digitally exposed recovery words. And pray no ransomware ever gets to your computer to deprive you of access...
