Is this 2FA cloud back-up strategy sound?

Since I’m on Android I use Aegis for my TOTP; what I did for it was I create local and cloud backups (in proton drive), and I wrote down my aegis password and keep it safe, this helps in case I need my totp backup to login to bitwarden. I also use security keys, so I can use them as 2fa for bitwarden, then login to proton drive with bitwarden and the security key, and then download my aegis backup as well. My one failure is not having adequate 2fa backups off-site for logging into bitwarden. I’m still working through that personally.
