Vrai ou faux message de Google?

Bonjour,
Je viens de recevoir ce message sur ma messagerie gmail:

xxx(mon prénom),

Someone recently tried to sign in to your Google Account, xxx@gmail.com. We prevented the sign-in attempt in case this was a hijacker trying to access your account. Please review the details of the sign-in attempt:

Location: Guatemala City, Guatemala Department, Guatemala

If you do not recognize this sign-in attempt, someone else might be trying to access your account. You should sign in to your account and reset your password immediately. Find out how at https://support.google.com/accounts/answer/41078?visit_id=637166660153783441-2112925508&p=reset_pw&rd=1

J'ai bien compris sa signification, mais je préfère laisser la version anglaise car sa traduction est incorrecte. Méfiant, je me demande s'il faut suivre la procédure suggérée ou s'il s'agit d'un piège.
Merci pour tout conseil.

P.S: Je ne connais personne au Guatemala!
