You only do this once per device.
Or use your passphrase:
Passphrase sign-in is turned off. To turn it back on, run recovery.bat on your laptop.
No peak flow readings in this range.
A passkey lets you sign in a new device with your fingerprint or face instead of the passphrase. Your fingerprint never leaves the phone.
Import a CSV in the same format as the export (columns: date, time, type, period, best_lpm, …). Duplicates are not detected, so import each file once.
Your readings stay on the server either way.
