Text message consent
How a Savenello member agrees to texted sign-in codes.
Savenello members opt in on their own Profile page at https://savenello.com/profile, under Sign-in and security, in the Texted sign-in codes form. The form shows the Savenello logo and name. The authenticator app stays available if they do not opt in.
To receive texts they enter a mobile number and check a box that starts empty. The box says: I agree to receive one-time sign-in codes by text message from Savenello. Msg and data rates may apply. Msg frequency varies, sent only when you request a code. Reply HELP for help or STOP to opt out.

They then press Text me a code. Savenello records the consent time and texts a one-time sign-in code only after that agreement, and only when the person requests a code. No marketing texts are sent.

The authenticator app stays available if you leave this off. Recovery codes still work.
