Good advice in this article. Keeping TOTP in a good password manager removes risk of making mistakes with the codes by tying it to the same auth sequence as the password. The assurance that the codes are securely stored, easy to use and to establish on a new trusted device lets services be used confidently which don’t allow vulnerable bypassing of credentials with easily purchased proofs (SSNs, street address etc.)

Backing up TOTP seeds encrypted is a good idea if you know what you’re doing.

It is a security-improving move when humans are factored in, not a trade-off between security and convenience.
