Thanks for sharing a potentially useful tool but I will not use it without a lot more details about how this browser extension secures the 2FA secrets from sketchy websites/ads.
Most trusted desktop password manager apps can manage and autofill OTPs in browsers as well, e.g. KeepassXC and 1password. (If you're making the tradeoff anyway, I think you may as well use a password manager you already trust with other secrets.)
