💡 Use cases: clearly communicating confirmation codes over the phone, spelling out passwords in customer service, reading license plates over radio, pilot communications, and any voice channel where letter confusion (B vs D vs P) is costly.
Passwords tips
For initial setup credentials, spelling out the password using NATO avoids transcription errors.
For passwords with special characters, you'll need to also add "exclamation mark", "at sign", etc. by voice.
Better practice: use a password manager and share via a temporary secure link instead of voice.
