This includes passwords, a PIN (personal identification number), or answers to security questions. SMS authentication is not typically used as a primary or sole authentication method, but it's commonly used as the second authentication factor in two-factor authentication (2FA) and multi-factor authentication (MFA).ДЄuthentication types are broken out into three main categories, with SMS authentication falling under the Possession factor: Passwords are the least secure authentication method and can be guessed, stolen or bought on the dark web, so they need to be reinforced. Presenting users with multiple options to verify their identity helps reduce fraud and defend against bad actors. What is SMS Authentication in Two-Factor Authentication (2FA) and Multi-Factor Authentication (MFA)? Let's look at how SMS authentication works and whether it is secure. SMS can also be used to authenticate a user's identity. Texts sent to your phone can be forwarded or synced with other devices to make sure you never miss a message. Since 1993, approximately 7,000 students have attended certification and re-certification courses at the center.Short message service (SMS), also known as text messaging, is something you may use every day with your friends and colleagues. The HMAC is located just south of Austin in Buda, Texas, in a 10,000-square-foot building containing eight laboratories.

With the addition of soils and base training to an existing successful program, the HMAC provides all required training and certification for TxDOT and Industry in the QC/QA field. The HMAC administers TxDOTвЂ™s approved training and certification for individuals in five levels of certification: SB 101, SB 102, SB 103, SB 201, and SB 202. The center recognizes the importance of the role soils and bases play in construction. In 2007, the HMAC began training and certifying technicians in Soils and Base. Many states have visited the center and have used it as a model to develop their own certification programs.

The teamwork philosophy that TxDOT and TXAPA used to develop the certification program has enabled the HMAC to gain national recognition as a superior program. Procedures for certification include a hands-on demonstration of test performance, evaluation of test performance by a certified evaluator, classroom participation, and a written examination. At the end of the three-year period, specialists are required to complete re-certification courses. The original certification is valid for three years. These levels include: field laboratory testing (Level 1A), quality management and mix design (Level 2), roadway testing (Level 1B), and in 2019 aggregates specialist (AGG101) was implemented. The intent of the program is to improve the quality and performance of hot mix asphalt pavements through knowledge and understanding of the product.Д¬urrently, the HMAC provides three levels of certification in testing and evaluating hot mix asphalt. The purpose of the Certification Program for Hot Mix Asphalt Specialists is to develop and maintain a pool of well-trained specialists for the state and contractors to design, test, and manage hot mix asphalt pavements. A joint TxDOT/TXAPA Steering Committee carries out oversight of the operation to ensure the integrity of the program meets the high standards originally stipulated. Today, the Texas Asphalt Pavement Association (TXAPA) manages and operates the center and certification program that meets TxDOTвЂ™s requirements and specifications. The Hot Mix Asphalt Center (HMAC) was developed to implement the certification program. Through this extensive process, they determined that a certification program for technicians involved in sampling, testing, and designing hot mix asphalt would play a major role in the success of the QC/QA specification. TxDOT called on the industry to assist them in the research, data analysis, and review of existing QC/QA specifications to generate a comprehensive specification. The development of the Texas Department of TransportationвЂ™s (TxDOT) Quality Control/Quality Assurance (QC/QA) Hot Mix Asphalt specification was a positive step toward improving the quality of hot mix asphalt pavements in the state.
