よくある質問

Is LastPass no longer safe?

It’s complicated. In 2022, hackers successfully stole encrypted user vaults. While your data remains unreadable もし you have a very strong Master Password (12+ characters), the company’s reputation was severely damaged. Many security experts now recommend open-source alternatives like Bitwarden instead.

Why are people leaving LastPass?

Two main triggers: trust and restrictions. The 2022 data breaches exposed concerns about their internal security culture. Additionally, changes to the Free plan in 2021 restricted users to only 1つ device type (computer OR phone), pushing many to find more generous free alternatives.

Why does Chrome no longer support LastPass?

Actually, Chrome still supports it. You likely saw a warning regarding the phase-out of “Manifest V2” extensions. LastPass has updated their extension to meet Google’s new “Manifest V3” standards. Simply update your Chrome browser and the LastPass extension to the latest version to resolve this.

Is LastPass still worth it?

For most users, probably not. The Premium plan costs roughly $36/year, but competitors offer similar security features for free or significantly less (e.g., Bitwarden is $10/year). Unless you are deeply integrated into their ecosystem, better value exists elsewhere.

What are the cons of LastPass?

The biggest downside is its history of security incidents. Beyond that, the Free plan is highly restrictive, preventing sync between your computer and phone. Customer support is often reported as slow, and because the code is closed-source, independent researchers cannot audit its security.

Is LastPass Authenticator good?

It is convenient but carries risk. It allows for easy “one-tap” logins into your vault. However, since it is tied to your LastPass account, getting locked out of your vault can also mean losing access to your 2FA codes, making recovery a nightmare.

How do I use LastPass step by step?

1. Install the browser extension. 2. Create an account and set a strong Master Password. 3. Log in to a website (like Facebook); LastPass will ask to “Save” the credentials. 4. Next time you visit, click the LastPass icon in the login field to autofill.
