Then for sure that will help you secured your wallets. Having multiple wallet is relatively good especially if you are holding huge number of coins. However, I am suggesting to secure the seed phrase not only in your laptop but also one should need a back up like a USB. This is way better because time to time laptop could go wrong or might be broken or damage over a period of time in its use.
I don't think it really relates to huge or small number of coins we own. No matter what how many coins we have, we should secure them all as best as possible. Small money with one person might be a huge one with others. Years ago, bitcoin is trash, but now only a single bitcoin worths a lot. Therefore, I think we should decentralize our coins with as safe storage as possible. 
Topic: How to find out your private key by SEED phrase. (Read 585 times)
Thank you for your very quick and comprehensive reply. I meant I want to decentralize my funds on different computers to reduce risks of losing all my money in worst case of hacks or data leaks. And I have plan to use only one laptop to do daily stuffs, the rest two ones will keep almost inactive or with very limited connections to Internet space

We all were noobs at one time or the other.
You can generate any number of wallets as you want on one computer. No need to use three different laptops.
If you already have those three wallets on three different laptops, then too you can export the seeds and import them on a single laptop.

I am noob, so can I ask stupid question?
Can I export three sets of seeds of three wallets on a single computer?
I meant if I have three laptops, in which I install three wallets, then backup seeds. Later, I use only one laptop to check each wallet by export three seed-sets on one laptop?

Useful guide but this advice near end i wouldn't agree that much. Piece of paper is easy to loose, to become unreadable or beign stolen.
If you want to use paper only, you need 3 copies, and good physical security to it.
It's okay to store it on a paper but you have to cover it with a plastic cover or you can laminate the paper so it can't be torn and it will prolong the durability of the paper and the seed. Also there is another way, save your seed in a device like computer, laptop that is not connected to internet the same as the op finding private key on a cold computer or a USB. It is prefer to have seed back up more than one back up in case you lose it. If you want to use paper only, you need 3 copies, and good physical security to it.
if you have created your mnemonic phrase (which wallets usually call seed) using a wallet then it is best to use that same wallet to recover your private keys and corresponding addresses because BIP-39 is one of those improvement proposals that has not been implemented the same way everywhere. for example Electrum uses its own method so if you enter your Electrum seed in Ian Coleman's tool you won't get anything out of it because it is incompatible.
7. You can use the keys in any official wallet.
Just a small correction.There is no such thing as a official wallet. There is no official bitcoin team recognizing wallets or explorers or anything. It's fully decentralized.
But you can use those keys in any DECENT wallet.
This is only good if in some cases you need private keys, mostly in case user want to restore some coins from losted / broken hardware wallet. Still before you do this, option is that you first try to restore some coins with seed (for coins that have such option).
For example you lost hardware wallet and you need to access coins, it is logical that you first want to recover most valuable coins. For BTC you can use Electrum (only downloaded from official site+signature verify), but also few others Electrum forks (LTC, DASH, ElectronCash). When you safely move all coins to new wallets (by send them in transaction), you can now play with rest of them by using iancoleman tool.
On this way you ensure safety of most valuable coins in case that you download fake tool or that you have some malware on your PC. It is also important that you do not use your main seed just to test this method, if you want to play / test it, just create new wallet / seed and use that.

Just found this post by accident and it contains some good advice.
However, there is still one attack vector that you did not mention/consider: Unless you read every single line of javascript on the offline site, you cannot be sure that the seed phrase was generated in a secure and completely randomized way. The iancoleman.io site is very reputable but it may have been hacked or compromised in some way, so that you are given a seed controlled by the attacker.
The remedy for this problem is to manually create your seed phrase, using physical and transparent sources of randomness. I have written a guide for this process, you can find it on seedpicker.net.

Very cool post, I've been doing this for years and I even learned something. Thanks for the useful thread. I'm certain in the right hands this may be a million dollar fix.
A word of advice: keep your SEED phrase on paper only.

I think you touched on area that where so complicated to me before and made it look easy. I have been have difficulty with my private keys as to regards the status quo
Oh really does it work? I just need some pictures of this one OP. This topic is great and I bet there could be a use for this one in the near future. Sometimes i lose my private key but still confident enough because I have my seed phrase. However, it would be good to have a way to generate private key and wallet address using seed phrase. It just need a pictures for this one for proving.
I will check with this one later maybe OP will provide pictures for this.

I did not know this. Thanks for such a useful tip. Anyone has tested this method? If you prepare a video too, it will be better and easier to understand.
Hello everyone, I want to bring some good to the forum and post this instruction, thanks to user Jurs for the tip.
I think most of those who are here do not need to explain what the SEED phrase is and how important it is to properly store it. When creating wallets you get a led phrase, this is a set of 12 18 24 words. Save the phrase is very important. Suppose for some reason you lost your keys, or didn’t know them initially (hardware wallets). How to restore them?
There is an English word list of the BIP39 standard, containing 2048 words and key generation protocols BIP32-44-49-84-141, which are used to create wallets. Knowing your seed phrase, you can get the private and public key corresponding to it.
Step by Step:
1. Download the latest BIP39 release: https://github.com/iancoleman/bip39/releases/
2. Install the downloaded BIP39 on a "cold" computer (a device that will never be connected to the Internet later).
An old laptop can be used as a “cold” computer, having previously prepared it, it is recommended that all transmitting devices (Wi-Fi, Bluetooth) be physically disconnected and the operating system is reinstalled. It is possible to use "Raspberry Pi" as a "cold" computer (it will be completely not expensive) https://en.wikipedia.org/wiki/Raspberry_Pi
3. Open the downloaded BIP39 in html, on the open page, in the BIP39 Mnemonic field, enter the entered phrase.
4. In the Coin field, enter the ticker of the desired coin.
5. In the Derived Addresses field you will see your Public Key and Private Key.
6. If you didn’t see your keys, or you don’t see everything, you’ll have to fill out the "Derivation Path" section.
Full instructions on how to register the path of the coin you need, following the link https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki
7. You can use the keys in any official wallet.
A word of advice: keep your SEED phrase on paper only.
Congratulations, you received your address and private key. If you entered a phrase not on a "cold" computer (not recommended), after receiving the keys, be sure to transfer the coins to other wallets.
The way is checked, everything works.
