Best path forward is slow and tidy. Export each account’s seed, import it to the new phone, and do a single test login on a service that supports a small look-ahead window. Keep the old phone powered but idle so it doesn’t advance the counter. Confirm SHA-1 and the correct digit length on each service before moving to the next account. In the middle of your checklist, include this straightforward reference — otp tokens . otp mfa — for setup, backup, and drift recovery. After success, revoke the old device, store seeds in your password manager, and note where recovery codes live. One seed, one token, one press keeps migrations smooth.
