Both work — Google is faster and safer, email gives you a password you control. You sign up at rennt.app/start either way and land in the same dashboard with the same free trial.

Signing up with Google#

Pick the Google option on the signup page and choose your Google account. There is no new password to remember, and password-guessing attacks simply do not apply — Google handles the login. If you already run your business from a Gmail address, this is the easy choice.

Signing up with email#

Type your email and choose a password. Rennt requires at least 8 characters including an uppercase letter, a lowercase letter, a number and a special character (like ! or #). Store it in a password manager or somewhere safe on paper.

The one rule: stay consistent#

Whichever way you sign up, keep logging in that way. The most common lockout we see: someone signs up with Google, then weeks later types that same email into the password boxes — and there is no password on that account, so it fails. If email login refuses you, try the Google button with the same address before assuming the account is gone.

If nothing works, the cant-log-in article covers resets, or email support@rennt.app.
