Great article. Seems like Authy is already becoming irrelevant to use anyway since it just presents 2FA codes which is already done by nearly all password managers.

Also, the migration here is only for 2FA codes on Bitwarden and later the author migrates to 1Password. I'm pretty sure you could choose to migrate altogether either on 1Password or Bitwarden since they both support 2FA codes.

If it were me, I'd just migrate to using Dashlane instead.

Yep, you could definitely choose to use either 1Password or Bitwarden for both passwords and 2FA codes. I addressed this point in the article. I'm willing to deal with the hassle of using two password managers to avoid putting them all in one place, providing some degree of protection if one gets compromised but not the other.
