That's right in the sense that sola scriptura shows us that in order to be saved ultimately, believers must get water-immersion (burial) baptized into Jesus' death for our sins (Mark 16:16; 1 Peter 3:21, Romans 6:3-11, Colossians 2:12, Galatians 3:27, Acts 2:38, Acts 22:16). If people believe with all their heart that Jesus Christ is the human/divine Son of God (Acts 8:37), they can get baptized anywhere there is water (Acts 8:36) into which they can be fully-immersed (buried) (Romans 6:3-11, Colossians 2:12). They need to make sure to be baptized in the name of God the Father; and of the Son, Jesus Christ; and of the Holy Spirit (Matthew 28:19, Acts 2:38). Believers can get water-immersion baptized at, for example, a Baptist-type congregation.
Besides getting water baptized, believers can get Holy Spirit baptized (Acts 11:15-16, Acts 10:44-46). They usually have to ask to receive the Holy Spirit (Luke 11:13b) baptism, for it is usually not given to them automatically at the moment that they become believers. That is why Paul the apostle asked some believers: "
Have ye received the Holy Spirit since ye believed?" (Acts 19:2).
Believers usually receive Holy Spirit baptism through prayer accompanied by the laying on of hands, subsequent to water baptism (Acts 8:15-17, Acts 19:5-6). Holy Spirit baptism won't result in speaking in tongues for everyone (1 Corinthians 12:30), but for almost everyone, as tongues are one of the Spirit's lesser gifts (1 Corinthians 12:8-11,28; 1 Corinthians 14:5). Many believers haven't yet experienced Holy Spirit baptism simply because they haven't yet asked for it, under the principle of "ye have not, because ye ask not" (James 4:2b). Many believers haven't yet asked for it because they have come under the influence of mistaken teachings which say that it is no longer in effect. Believers can get hands laid on them to receive Holy Spirit baptism at any Pentecostal-type congregation, or at any charismatic-type congregation, which can be of almost any denomination (even Catholic).

Regarding water baptism, some people feel that it can't be required for salvation, because baptism is a work, and salvation isn't based on works, but on faith alone (Ephesians 2:8-9). But baptism is a kind of circumcision (Colossians 2:11-13, Philippians 3:3, Romans 2:29). Just as Abraham, who is a model for Christians, was initially saved by faith alone, prior to his circumcision (Romans 4), so Christians are initially saved by faith alone (Ephesians 2:8-9, Titus 3:5, Romans 4:2-5), prior to their baptism (Acts 8:36-38, John 20:31). But just as Abraham was ultimately saved by his works (James 2:21-24), so Christians will be ultimately saved by their works (Romans 2:6-8, James 2:24, Matthew 7:21, Matthew 25:26,30, Philippians 2:12b, Philippians 3:11-14; 2 Corinthians 5:9, Hebrews 5:9, Hebrews 6:10-12; 2 Peter 1:10-11, John 15:2a; 1 John 2:17b), which must include getting water-immersion (burial) baptized (Mark 16:16; 1 Peter 3:21, Romans 6:3-11, Colossians 2:12, Galatians 3:27, Acts 2:38, Acts 22:16).
