Centering text in a responsive way

Question

Good afternoon! I am building a project that currently has the following problem: The text Authentication is not getting totally centralized. I thought to use margin-right (this solution works only in the resolution of my machine). I wonder if anyone can help me, follow code:

CSS:

*{
margin: 0;
padding: 0;
}

.logos-container {
    display: flex;
    flex-direction: row;
    flex-wrap: wrap;
    align-items: center;
    justify-content: left;
    padding: 12px 8rem;
    text-transform: uppercase;
    font-family: 'Roboto', sans-serif;
    font-weight: 700;
    font-size: 1rem;
    text-align: center;
    color: #001C44;
    border-bottom: solid 1px #cdd1d3;
    box-shadow: 0px 3px 5px -1px rgba(50, 50, 50, 0.35);
    margin-top: 5px;
}
.logos-container img {
    height: 3rem;
}
.logos-container h2 {
    flex: 1;
}
.loginContainer{
    background: url("https://i.ibb.co/NnfNFJ1/fatura.png") no-repeat left 20px;
    background-size: 24%;
    height: calc(100vh - 5.25rem);
}
.footer {
    font-family: 'Roboto', sans-serif;
    font-size: 14px;
    font-weight: 300;
    padding: 0 2rem;
    background: #f5f5f5;
}
.footer a {
    text-decoration: underline;
    color: #9B9B9B;
}

<div class="page">
    <div class="logos-container">
        <img src="https://i.ibb.co/njPs6xJ/min.png" class="logomin" alt="Ministerio da Educação" />
        <img src="https://i.ibb.co/mcKb85g/aetr.png" class="logoaetr" alt="Agrupamento de Escolas Tomaz Ribeiro" />
        <h2>Autenticação</h2>
    </div>
    
    <div class="loginContainer">
    </div>
    
    <div class="footer">
        <a href="https://google.pt/">Esqueceu a sua senha?</a> <span>Versão: 1.0</span>
    </div>
</div>

Non-centralized text:

Looks like you need the flex Direction column, no need to justify to the left

*{
margin: 0;
padding: 0;

.logos-container {
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
text-transform: uppercase;
font-family: 'Roboto', sans-serif;
font-weight: 700;
font-size: 1rem;

border-bottom: solid 1px #cdd1d3;
box-shadow: 0px 3px 5px -1px rgba(50, 50, 50, 0.35);
margin-top: 5px;
}

.logos-container img {
height: 3rem;
}
.loginContainer{
background: url("https://i.ibb.co/NnfNFJ1/fatura.png") no-repeat left 20px;
background-size: 24%;
