Can Someone Tell if You Have Read Their Email
I think someone I know has hacked my Gmail account. What should I do? Valeria
This is a relatively common question. Other contempo examples include "Someone is using my Gmail account to steal my data on a game. How do I go rid of him?" from Rodimus Ghost, and "My girl is using my Gmail account. How practise I stop her?" I don't recollect getting these queries about other email services.
My usual response is: "How do you lot know?"
At that place might exist emails in the Sent Post folder that you didn't write, though hackers can cover their tracks by deleting copies of sent emails. Notwithstanding, incoming emails are not an indicator. I've had emails from Instagram, GoCompare, Barclaycard Business organization, Apple tree, Prattville YMCA and many other organisations where people accept entered my Gmail accost, probably by mistake. It doesn't hateful they have accessed my account.
The best way to tell if someone else has used our account is to roll downwardly the Gmail inbox and wait for "Last business relationship action" in the lesser right. Clicking on Details produces a nice table that shows how someone accessed the account (browser, mobile, POP3 etc), their IP accost, and the date and fourth dimension. You should recognise any sessions that aren't yours.
In fact, Gmail volition, by default, notify you of any unusual activity. You lot may become an alarm if y'all log on with a new device or from a different country. These alerts can be annoying merely they increase your security. Don't turn them off.
You can likewise check the Recently used devices page, which lists all the PCs, phones and tablets used in the previous 28 days. Once again, it should be obvious if whatever of them are not yours.
Double-check Settings
There are uncomplicated means to read someone else's emails without leaving obvious traces. These are controlled from Gmail's Settings, which you can find by clicking the cogwheel in the acme right.
On the Settings page, click Accounts and Import and go to the penultimate entry: "Grant access to your business relationship". Someone could click "Add together an email account", enter another Gmail address, and access your emails from that account. They can keep these emails marked as Unread even if they've read them.
Next, click Forwarding and POP/IMAP and review the top section on mail forwarding.
Electronic mail services allow users to frontward all incoming emails to another e-mail address, and I retrieve everyone should do this. I have Gmail forward all my emails to my business relationship at Microsoft's Outlook.com. As a result, I can all the same read and reply to emails fifty-fifty if Gmail is inaccessible. Further, if Gmail locked me out, I'd still have copies of emails going back to April 2004.
So, if you can access someone'south mailbox, you can ready mail forwarding to an accost that yous command, and they'll probably never discover. Brand sure nobody has done that to you.
If you only read Gmail in a web browser, you could also disable the Pop and IMAP admission features. This would provide a small increase in security, just I don't recommend it. In fact, at that place are advantages to using a PC email program such as Microsoft Outlook, Thunderbird or eM Client to collect Gmail using the IMAP protocol. These programs have more than features than the spider web version of Gmail, and they shop emails on your PC so that you can hands admission them offline. IMAP leaves the original emails online, then y'all can still access them using different devices. (Yes, you can besides install "Gmail Offline" via the Offline tab.)
Remember to relieve whatever changes before switching tabs.
Password security
Once you lot are sure your mailbox is not being hacked, change your password to keep other people out.
In Gmail, become back to Accounts and Import and click "Change password".
Cull a potent countersign or passphrase that includes numbers and upper-instance characters. Gmail requires at to the lowest degree eight characters, but aim for 12 or 16 or even more. Longer is amend. It won't be random, unless you use a countersign managing director, merely avert family names, names of pets, birthdays, sports teams and other obvious elements.
For convenience, your browser or email program can retrieve your password. If you let this, your email is simply as secure equally your PC. Anyone who tin admission your PC can access your email.
Nowadays, of class, the simplest fashion to hack someone'due south email is to employ a phishing attack. In this example, someone sends you lot a link in an email that pretends to come from Google. Clicking the link opens a browser tab where "Google" asks you to log in with your email accost and password. The attacker harvests the results.
If you're going to leave your PC unattended or fall for a phishing attack, information technology doesn't matter how strong your countersign is.
Practise the two-step
If someone can access your Gmail account, they tin can change your countersign and lock you out. You can forbid this by using "two-stride verification". With Gmail, this ordinarily means Google will text a code to your mobile phone. This is fine until y'all don't have a signal or lose your phone. Gmail therefore asks for a back-up phone number. (Landlines work: you get a voice message.) Gmail also allows you to impress out a minor set of verification numbers that yous can utilise when travelling.
Google provides an alternative to SMS in the form of Google Authenticator, a gratis app for Google Android devices and Apple iPhones and iPads.
You can likewise simplify two-footstep verification slightly past using "application specific passwords". For example, if you access Gmail via a smartphone app or an email client that can't handle ii-step verification, you can request a divide countersign for each electronic mail plan on each device. It only has to be entered once.
To use these actress security features in Gmail, go to Accounts and Import, click "Other Google Account settings" and and then "Sign-in & security". This provides access to password changes, two-step verification, and account recovery options.
Account recovery
What if your password stops working and you can't go into Gmail? The traditional approach to account recovery is to enquire for some personal information, such every bit your mother'south maiden name. This enabled people to hack email accounts by using information gleaned from social media accounts. You tin can prevent this by using random letters or something obscurely incorrect – "Mother's maiden name: Quetzalcoatl" – but then you lot have to retrieve the answers.
Google's recovery options include a phone number, another e-mail address and a security question. It also likes to ask when the account was opened and when you last used it.
Yous may be able to find out when yous created your Gmail business relationship by searching for (in my case) before: 2004/04/xv, or any date in YYYY/MM/DD social club. That won't work if you deleted your welcome message, but vary the date to find the oldest bulletin you can.
Account recovery is the only style to get your Gmail back if you forget your countersign or a hacker changes information technology. Just it doesn't always work, and you may exist told that "You weren't signed in because Google couldn't confirm that xxxxxxxx@gmail.com belongs to you lot."
Then – as another reader, Paul, found earlier this yr – you end upward in a "failed online recovery loop. No contact eye. No online chat. No contact details at all." It looks as if there'southward cypher you can exercise except open a new account, modify all your online passwords and email addresses, and hope goose egg bad happens.
