How Do You Say “Sign In” in Spanish?

The standard Spanish translation of “sign in” for an existing online account is “iniciar sesión.” To say “sign in to your account,” use “iniciar sesión en tu cuenta” in an informal message or “iniciar sesión en su cuenta” in a formal instruction.

The Most Common Translation of “Sign In”

For websites, apps, and other account screens, “iniciar sesión” is the most common translation of “sign in.” It means starting a session with an account that already exists, usually by entering a username or email address and a password.

Readers asking “how do you say sign in in Spanish?” or “what is sign in in Spanish?” usually need this account-related phrase. A button labeled “Sign In” can therefore appear as “Iniciar sesión.” The shorter word “Entrar,” meaning “Enter,” also appears on some interfaces, but “Iniciar sesión” is clearer and more specific.

Spanish wording can vary by country and by the amount of space available on a screen. “Acceder,” meaning “Access,” may be used for account entry, while “Ingresar” is common in parts of Latin America. These alternatives can be correct, but “Iniciar sesión” is the safest general translation for account access.

“Iniciar sesión” for Account Access

“Iniciar sesión” is a verb phrase used when someone enters an existing account. The phrase may appear on a button, in an instruction, or in an error message.

• Sign In: “Iniciar sesión”
• Sign in to your account: “Inicia sesión en tu cuenta”
• Please sign in: “Inicia sesión, por favor”
• You must sign in to continue: “Debes iniciar sesión para continuar”
• Unable to sign in: “No se pudo iniciar sesión”
• Sign out: “Cerrar sesión”

For formal instructions, “Inicie sesión en su cuenta” is appropriate. For an informal instruction to one person, “Inicia sesión en tu cuenta” is natural. If the question is “how do you say sign into your account in Spanish?”, either version may fit; the choice depends on whether the message uses formal or informal language.

A complete sign in Spanish translation should preserve the action, not translate each English word separately. In this context, “sign” does not mean writing a signature, and “in” does not need its own direct translation.

When “Registrarse” Means Something Different

“Registrarse” means “sign up” or “register.” It tells a person to create a new account, so it is not interchangeable with “iniciar sesión,” which tells a person to enter an existing account.

• Use “Iniciar sesión” when the person already has an account.
• Use “Registrarse” when the person needs to create an account.
• Use “Crear una cuenta” for the especially clear instruction “Create an account.”

This distinction matters on a login screen. Translating both “Sign In” and “Sign Up” as “Registrarse” could send an existing user into the account-creation process. A screen containing both actions can label them “Iniciar sesión” and “Registrarse” or “Crear una cuenta.”

How to Translate “Sign” as a Noun or Verb

The English word “sign” has several meanings, and each meaning has a different Spanish translation. The Spanish word for sign in an account interface is part of the phrase “iniciar sesión,” but that phrase does not describe notices, road signs, or signatures.

• A posted sign or notice can be “un letrero,” “un cartel,” or “un aviso,” depending on its form and purpose.
• A road sign is “una señal de tráfico” or “una señal de tránsito,” depending on the region.
• A sign, signal, or indication can be “una señal.”
• A signature is “una firma.”
• To sign a document is “firmar un documento.”
• Sign here is “Firme aquí” in a formal instruction or “Firma aquí” in an informal one.

Someone searching “how do you say sign in Spanish” may be asking about the noun “sign,” not the login command “sign in.” The surrounding sentence determines whether the right word is “letrero,” “señal,” “firma,” “firmar,” or “iniciar sesión.”

Common Spanish Login Terms

Login terms often appear together, so recognizing the related labels can make a Spanish account screen easier to use.

• Username: “nombre de usuario”
• Password: “contraseña”
• Email address: “correo electrónico”
• Account: “cuenta”
• My account: “mi cuenta”
• Forgot password?: “¿Olvidaste tu contraseña?” or the formal “¿Olvidó su contraseña?”
• Remember me: “Recordarme”
• Verification code: “código de verificación”
• Continue: “Continuar”
• Cancel: “Cancelar”
• Sign out: “Cerrar sesión”

“Inicio de sesión” is the noun form meaning “login” or “sign-in.” For example, “datos de inicio de sesión” means “login details.” By contrast, “iniciar sesión” is the action: “to sign in.”

Choosing the Right Phrase

To decide how to translate sign in to Spanish, first identify what the person is being asked to do. The correct phrase changes with the setting.

1. For a website or app account, use “Iniciar sesión.”
2. For the instruction “Sign in to your account,” use “Inicia sesión en tu cuenta” informally or “Inicie sesión en su cuenta” formally.
3. For an attendance sheet or visitor log, use “registrarse,” “anotarse,” or an explicit instruction such as “Escriba su nombre,” meaning “Write your name.” The best wording depends on what the sheet asks the visitor to provide.
4. For a posted notice, translate “sign” as “letrero,” “cartel,” or “aviso,” based on the type of notice.
5. For a road sign, use “señal de tráfico” or “señal de tránsito.”
6. For a request to add a signature, use “firmar.” For “Sign here,” use “Firme aquí” formally or “Firma aquí” informally.

For most searches such as “how to say sign in Spanish,” “Spanish word for sign in,” or “how do you say sign in in Spanish,” the intended account translation is “iniciar sesión.” Use a different term only when “sign” refers to registration, attendance, a notice, a signal, or a signature.
