If you are a Windows user, I would recommend the QNAP range of NAS server devices, as these have more impressive hardware and the slightly more technical information is available straight away. It gives you few options, is far less flexible and though a monthly fee of £9.99 seems low (especially compared with £199 to buy your own NAS) after using this service for a year or two, you are throwing money away and still need somewhere for your data to go if you ever choose to abandon your Google Drive account. 3RD Party Cloud providers are a valuable service and indeed, using them as means to backup your NAS as a secondary backup (Synology, QNAP, Asustor etc all support 3rd party cloud migration), but as a primary means of cloud storage, I think Google Drive is a short-term answer. If you are on a shoe-string budget and are looking for fast, cheap short term cloud storage, then Google Drive is a good choice. I still genuinely believe that NAS is much, much better value for money and gives you everything that a cloud service like Google Drive does, for far, far less money in the long run – but that is the point, the ‘long run’. When it comes down to it, you need to choose which cloud option gives you the services you need. That user can share files (send links etc) but ultimately there is one user who can access the Google Drive account and typically you can only synchronize 1 PC and 1-2 Mobile devices to an account. Whereas most cloud services like Google Drive only give you ONE login and support only 1 user. per users – just set it up and practically unlimited users. From that point on you can access the NAS via the network/internet/mobile/anywhere in the world with just your login and password! What gives NAS an advantage over Google Drive, is that NAS features 2 step verification, unique AES-256bit encryption both locally and over the internet and (most importantly of all) a NAS can be access by HUNDREDS of users, each with their own login credentials, quota of storage space, completely controllable file access privileges and at NO ADDITIONAL COST. Internet access is kept safe and secure with a combination of their own NAS domain support and simply requires you to create a free account and to link your NAS with that account for the first time.

On multiple occasions, Wonder said he wrote this song in direct response to a 1979 bill to create a nationwide Dr.It’s noteworthy to mention that Wonder began this campaign when he was just 17. In other words, Stevie Wonder used the song as part of his campaign to create a national holiday in honor of Dr.(the same place Martin Luther King made the unforgettable “I Have a Dream” speech back in 1963) to get the holiday legalized. Over 100,000 people attended this event, and of course Stevie performed “Happy Birthday” at the rally. As such, on 15 January 1981 Stevie Wonder organized a rally at the National Mall in Washington D.C.

3/20/2024 0 Comments Google authenticator backup codesMethod 1: Recovering codes from your backup In the following sections, we will explore various methods you can use to recover your codes based on different scenarios. Having a plan in place and understanding the different methods available for code recovery is essential to ensure you can regain access to your online accounts swiftly and securely. These are just a few examples of why you might need to recover codes from Google Authenticator. Multiple devices and backups: If you have multiple devices that use Google Authenticator, you might want to sync the codes across all devices or create backups to ensure you have access to the codes even if one device is lost or damaged. It’s crucial to have a recovery plan in such situations. Recovery after a factory reset: If you perform a factory reset on your device, you will lose all the data, including your Google Authenticator app and its stored codes. Switching devices: When switching to a new device, you’ll need to transfer your Google Authenticator codes to ensure you can continue using two-factor authentication with your accounts. If this happens, your codes might become inaccessible, and you’ll need to find a way to recover them. This can be a real problem if you don’t have other ways to log in to your accounts.Īpp malfunction or data corruption: Though rare, it’s possible for the Google Authenticator app to malfunction or experience data corruption. Without these codes, you won’t be able to log in to your accounts.Īccidental deletion of the app: If you accidentally delete the Google Authenticator app from your device without having a backup, you will lose all your codes. Here are a few common scenarios:ĭevice loss or upgrade: If you lose your device or upgrade to a new one, you might lose access to the codes stored in Google Authenticator. While the app is designed to provide a secure and convenient way to access your online accounts, situations can arise that require you to recover your codes. There are several scenarios where you might need to recover codes from Google Authenticator. Why would you need to recover codes from Google Authenticator? Fortunately, there are several methods available to recover codes from Google Authenticator, which we will discuss in detail in the following sections. Keep in mind that while Google Authenticator is an excellent tool for securing your accounts, it’s essential to set up backups and ensure you have a plan in place to recover your codes in case of device loss or app deletion. By enabling this app for your accounts, you significantly enhance the security of your sensitive data and reduce the risk of unauthorized access. Google Authenticator is widely used by various online services, including social media platforms, email providers, financial institutions, and more. This offline capability ensures that you can access your accounts even in situations where internet connectivity is limited or unavailable. This means that even if you don’t have an internet connection, you can still generate and use the codes. One of the primary advantages of using Google Authenticator is that the codes are generated offline on your device. This two-factor authentication process adds an extra layer of security, making it extremely difficult for unauthorized individuals to access your accounts, even if they have your password. When you log in to your accounts, along with your password, you are also required to enter the current six-digit code provided by Google Authenticator. Once activated, the app generates a new six-digit code every 30 seconds. This synchronization is done using a QR code or a secret key provided by the service. When you enable Google Authenticator for an online account, the app synchronizes with the website or service provider. It is available for both iOS and Android devices and works by generating unique security codes, known as Time-based One-Time Passwords (TOTP). Google Authenticator is a free app developed by Google that adds an extra layer of security to your online accounts.
