Here is a neutral and interesting summary of the provided text in one paragraph: One-time passwords (OTPs) are an effective method of two-factor authentication that provide greater protection from fraud and data leaks by replacing static passwords with time-sensitive, single-use codes. Customers receive OTPs via email or SMS to verify their identity during login attempts, making it more difficult for hackers to access accounts easily. The use of OTPs enhances account security, reduces fraud and cybercrime, and simplifies the customer journey by providing a convenient and cost-effective way to authenticate users. With various options available, such as hash-based one-time passwords (HOTP) and time-based one-time passwords (TOTP), organizations can choose the best solution for their needs, including Twilio Verify, which offers easy deployment of OTPs through SMS, WhatsApp, voice, or email.
